The design contains an active power factor correction circuit for universal voltage input as well as a ballast control circuit using the IR21592. The design also includes a PIC16F628 microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI). Other features include EMI filtering, transient protection and lamp fault protection. IRPLDIM2a Digitally Addressable Lighting Interface (DALI) The Digital Addressable Lighting Interface (DALI), international standard prlEC929, is a communication protocol and method to interface lighting units on a 2-wire network. The DALI protocol is 16 bits and supports addressing up to 64 ballasts individually, 16 groups or broadcasting to the entire lighting network. Aside from the protocol, DALI supports fading, logarithmic dimming, scenes and fault detection. The DALI allows for a complete lighting environment to be controlled and managed efficiently. The DALI can control (transmit and receive) up to 64 different ballasts with the same control system, transmitting instructions to single ballasts or to a group of ballasts. The ballast provides eye sensitive dimming over a wide range (1-100%). Various operating parameters can be changed and stored dynamically within the ballast memory. For example, scene levels can be set for different groups of ballast. Also, maximum brightness, minimum brightness, fade-time and several other features can be set as desired. Another feature is the ability to diagnose problems such as lamp failures. Perfect Light Quality By means of digital control, the light level can be adjusted very precisely according to individual lighting needs. The DALI includes 256 levels of brightness and a logarithmic dimming curve (Figure 2). The use of this curve allows for better control at lower light levels where the human eye is more sensitive.

A block diagram of the design is shown in Figure 3. The EMI filter blocks ballast generated noise. The power factor correction is used for sinusoidal input current and a regulated DC bus. The ballast control section provides frequency modulation control of a traditional RLC lamp resonant output circuit for preheating, igniting and ballasting the lamp. It is easily adaptable to a wide variety of lamp types. The digital control section provides the Digitally Addressable Lighting Interface (DALI) and the necessary circuitry and software to perform closed-loop dimming, lamp fault detection, shutdown and auto-restart.

The ballast control circuit uses the IR21592 Dimming Ballast Control IC programmed by the PIC16F628 microcontroller. The IR21592 controls the ballast according to the signals received from the microcontroller. The microcontroller is connected to the ballast and the IC to receive diagnostic signals. The communication between the ballast and the external world is done with two signals: TX (digital serial signal transmitted from the network to the microcontroller) and RX (digital serial signal from the microcontroller to the network). This system allows the ballast to communicate bi-directionally with the network (a PC or generally a DALI system). A digital interface assures high voltage isolation between DALI inputs and the resonant lamp output stage. The microcontroller manages the communication between interface and ballast IC. The complete circuit is shown in Appendix A. In the circuit thick races represent high frequency and high current paths. Lead lengths should be minimized to avoid high-frequency noise problems. Appendix B shows the Bill of Materials. www.irf.com 3 IRPLDIM2a Power Factor Control The power factor correction section consists of a Power Factor Controller IC (IC1), MOSFET (M1), inductor (L2), diode (D2), capacitor (C6) and additional biasing, sensing and compensation components (see Appendix A: schematics). The power factor correction circuit is a boost converter type running in critical conduction mode. This means that the inductor current discharges to zero each cycle before the boost MOSFET is turned on. The ST L6561D PFC IC is used which shapes the input current to the input voltage while regulating the DC bus voltage at 400 VDC. The IC is chosen for its minimal component count, low start-up supply current and robust error amplifier. Ballast Control The ballast control section is built around the IR21592 Dimming Ballast Control IC (IC2). The IR21592 is used for preheating and igniting the lamp, controlling the lamp power and detecting fault condition (over temperature, over current, VCC fault and DC Bus/ AC line fault). The IR21592 contains a voltage-controlled oscillator (VCO) controlling the half-bridge frequency while maintaining a 50% duty cycle, a high voltage half-bridge driver, an amplitude control, fault circuit and an analog dimming interface. To preheat the lamp, the amplitude control feature of the IR21592 is used, which regulates the resonant tank current during the Preheat period. The VCO starts at maximum frequency and then decreases the frequency until the voltage at the CS pin is equal to the programmed voltage at the IPH pin. The VCO is then adjusted internally (and therefore the frequency) such that the inductor current remains constant until the external capacitor on pin CPH charges above 5.1V. The preheat current (voltage) can be adjusted by increasing or decreasing the resistor on the IPH pin (RIPH) and the preheat time can be adjusted by increasing or decreasing the capacitor on pin CPH (CCPH). When pin CPH exceeds 5.1V, the IR21592 enables the over-current protection and the next cycle where the CS pin exceeds the internal threshold of 1.6V the half-bridge is disabled. The VCO voltage decreases to a minimum value and the IR21592 starts to decreases the frequency to a minimum frequency which is set by the external resistor on pin FMIN (RFMIN) and the current sensing resistor RCS. In this way it generates a high voltage for igniting the lamp. This voltage can be adjusted by adjusting RCS. When the lamp is successfully ignited, The IR21592 regulates the phase angle of the inductor current with respect to the half bridge voltage to regulate the lamp power. This is done by measuring the zero crossing of the current and regulating it against the reference angle from the dimming interface. The IR21592 provides a 0-to-5 VDC dimming interface which converts the analog input voltage to an internal phase angle reference for controlling the lamp power. The DIM pin is a high impedance analog control input and the RMAX and RMIN pins set the maximum and minimum angles boundaries. The RMIN resistor sets the minimum lamp power at 1% when VDIM=0V and the RMAX resistor sets the maximum lamp power at 100% when VDIM=5V. Digital Control The digital control section is built around the PIC16F628 Microchip microcontroller. This microcontroller acts as an interface between the IR21592 ballast controller and the Digitally Addressable Lighting Interface (DALI). Data is transmitted to the unit and the PIC16F628 collects the data through an isolation circuit. It then interprets the data and sends the appropriate signals to the ballast controller IR21592 if necessary or sends information back to the DALI. The PIC16F628 also performs fault detection and disables the IR21592 if a fault is present. 4 www.irf.com IRPLDIM2a BALLAST DESIGN The ballast design incorporates two parts, hardware and software. The ballast controller design portion incorporates most of the hardware design. The digital design control portion incorporates most of the software design. Appendix A shows the complete schematic and Appendix B the Bill of Materials. The Ballast Controller Design The design of the Ballast control portion of the circuit has been accomplished in International Rectifier’s Reference Design IRPLDIM1. Refer to this for waveforms and specific calculations regarding the ballast controller portion of this design. Signals of the IR2159 The communication between the microcontroller and the IR21592 is done with four signals, as shown in Fig. 4. These signals are used for digital dimming (RB3), turning the ballast on or off (RB4), and fault detection (RB5 & RB6). The microcontroller controls the IR21592 by the following 3 pins: pin SD for shutdown of the IC (active high), pin FMIN used for fault detection (0 if the IC is Lamp in fault mode) and pin DIM to control the brightVDD Out ness. The microcontroller receives lamp inforR17 mation by the signal Lamp-out, connected to the lamp. 1 16 If 0 Lamp OK If 1 Lamp Fault C11 TR data signal from the network to the micro RA4 4 RA5 5 VSS 7 Interfac e with Optos RX data signal from the micro to the network RA3 3 6 RA1 RB0 PIC16F628 2 RA2 RB1 18 RA0 17 RA7 16 RA6 15 VDD 14 RB7 RB6 HO 2 VCO VS 15 3 CPH VB 14 4 DIM VCC 13 5 MAX 6 MIN LO 11 7 FMIN CS 10 8 IPH SD 9 RDIM If 0 IC OFF If 1 IC OK IR21592 1 VDC R16 COM 12 13 12 8 RB2 RB5 11 9 RB3 RB4 10 TURN ON IC TURN OFF IC R25 Digital Signal CMOS DALI Signal C17 1.25V 2.5V VSS 3.75V Fig. 4 Micro/IR21592 Communication www.irf.com 5 IRPLDIM2a The shutdown signal (RB4) enables or disables the IR21592. When high, the lamp is off and the IR21592 is disabled with minimal current flowing. When low, the lamp is on. The PIC16F628 has control of this line and determines if lamp should be on or off based on fault conditions and user requested settings from the DALI. There are two signals used for fault detection, lamp-out (RB6), and fault (RB5). The lamp-out signal indicates the presence of a lamp or lamp fault. When the lamp is removed the lamp-out signal is pulled up to VDD by the pull-up resistor R17 and the software forces the IR21592 to shutdown. When the lamp is changed, this pin goes to 0 Volts, the microcontroller turns the IR21592 on again and the lamp re-starts automatically. Other fault conditions are indicated by the fault signal (pin FMIN of the IR21592). A low on the fault signal indicates that the IR21592 is in a fault state (the IR21592 turns off automatically in fault conditions such us VCC fault, over-current, failure to strike or low AC line and will remain in this FAULT state until the IC is reset. The IR21592 requires a 0.5-volt to 5-volt analog voltage (in pin DIM) to perform dimming, thus 0.5 volts corresponds to the 1% arc power level and 5 volts corresponds to the 100% arc power level. The PIC16F628 provides a pulse width modulated signal on pin RB3 that is filtered with a single RC network (R25 and C17). This provides an analog voltage for dimming. The micro can change the dim voltage from 0.5V to 5V by changing the duty cycle and therefore generate 256 different voltage levels for the IR21592. To conform to the digital dimming requirements, the output is logarithmic rather than linear. Since the human eye is much more sensitive to lower light levels than high levels, the logarithmic output appears to be linear. Therefore the PIC16F628 is programmed to produce a logarithmic voltage and the IR21592 drives the lamp arc power (Figure 5). Logarithmic Voltage Output Logarithmic Arc Power Output 5 % Arc Power Output 100 Voltage Output 4 3 2 1 80 60 40 20 0 0 85 115 145 175 205 235 85 115 145 175 205 235 Digital Input Digital Input Fig. 5 Dimming Chacteristics The microcontroller can also change the fade time by controlling the speed in which the duty cycle changes. The relation between light level and dim level can be tuned according to specific needs. The minimum light level can be changed by adjusting RMIN, and the maximum level can be changed adjusting RMAX. RMIN sets the lower phase boundary corresponding to minimum lamp power when VDIM = 0.5V, and RMAX sets the upper phase boundary corresponding to maximum lamp power when VDIM = 5V. RMAX must be set after RMIN. The software The software to implement the DALI is quite large but simple to understand when broken into some elementary functional blocks. Figure 6 outlines the basic flow of the software in its most simplified form (the details source code is available in a CD enclosed with the Reference Design Kit). 6 www.irf.com IRPLDIM2a Upon entry into the program after setup the microcontroller is held in a loop. While in this loop the microcontroller is checking for errors, plus it is polling the communications circuitry for incoming data. If valid data is received, it is filtered to determine if the address matches the defined address for the ballast, if the group matches the defined group memberships, or if the data is a broadcast command. Also, the type of command is filtered into two basic choices, standard or special. Once filtered, the program immediately vectors to the appropriate command and executes. All of the commands are divided into four general categories including arc power control commands, configuration commands, query commands, and special commands. Within each category the commands are divided again according to related functions. The arc power control commands are the most commonly used in a functioning lighting system. Within any of these commands appropriate signals are sent to the ballast controller to adjust light level via pulse width modulation. This includes scene level selections. Also many of the commands in this group select the shutdown bit, depending on the definition of the command. Configuration commands are used to setup the ballast. Examples of such settings include setting minimum and maximum lighting thresholds, fade times and rates, groups, and scene levels. Generally data is stored in an EEPROM storage area where it is maintained regardless of the power conditions. Query commands are used to get feedback from the ballast. All of the settings can be queried. Even more useful, the status of the ballast is available. Information about fading, the lamp, general faults, and power is available through the appropriate query command. Special commands are unique. These commands are immune to addresses; thus all ballasts on the Digitally Addressable Lighting Interface respond to a special command. All the functions for finding new ballasts or ballasts that have no addresses are available. Uploading information to the ballast, typically settings, is also available in the special command set. Fig. 6 Program Flow www.irf.com 7 IRPLDIM2a Isolation and the Signals for DALI The Digitally Addressable Lighting Interface is optically isolated from the microcontroller. Fig. 7 shows the connections between DALI and microcontroller. RB0 ENABLE RB2 TX_DALI RB1 RECEIVE-DRIVE + DALI - RA1 RX_DALI RA2 MICRO-CONTROLLER Fig. 7 DALI and Micro Controller connections The two wires from the DALI are converted to four signals. Two of the four are the transmit signal (RB2) and receive signal (RX_DALI). The other two signals are the communications-enable (RB0) signal and the receivedrive (RB1) signal. The transmit signal and the receive signal directly correlate to the levels seen on the Digitally Addressable Lighting Interface. For receiving higher voltage logic on the DALI is translated to 5 volt logic at the micro controller, and for transmission, the 5 volt logic is translated to the higher voltage logic on the DALI. The ballast achieves very low power by controlling the communications circuit with the communication-enable signal and the receive-drive signal. During normal operation the PIC16F628 enables the communication circuitry with the communication-enable signal. With this signal there is enough current, less than 100uA, to indicate when data is being sent to the ballast, but not enough current to accurately transfer the data. Upon detection (done by a S/H built into the PIC16F628) the receive-drive is asserted to raise the current above 500uA to achieve good signal transfer across the isolation. The receive-drive signal is only enabled long enough to transfer all the data; then it is disabled (see waveforms in figure 8). This method strongly reduces the power/current use. The comparator built into the PIC16F628 is used to set the threshold for detection of the incoming data. The signal RA2 is used as threshold for the comparator. 8 www.irf.com IRPLDIM2a Receive signal Receive-drive signal RB1 Communications-enable RB0 Fig. 8 Dali and Micro-Conttoller signals Shutdown and Low Power With shutdown there are some unique power conditions. With the shutdown line low and the lamp ignited, the PIC16F628 derives its power from the charge pump of the IR21592. The charge pump provides enough current for the microcontroller to run at its internal frequency of 4MHz during normal operation. When the shutdown line is asserted the IR21592 is disabled, and the charge Receive signal pump is no longer functioning. Current is drawn directly from the high voltage DC line through a high value resistor. The micro controller is put to sleep during this Receive-drive signal RB1 time to minimize current draw and power dissipation. To receive data, which requires significant current, the Communications-enable PIC16F628 wakes up and starts the charge pump of RB0 the IR21592 long enough to process the command, typically less than 25ms, but not long enough to ignite the lamp (see waveforms in Figure 9). Doing this unique management minimizes power dissipation during shutSD pin IR21592 down.
