This high performance power system building block satisfies a broad spectrum of requirements and agency standards. 2.1 If the bus voltage is less than 200V as the slope nears zero, the voltage doubler is activated, and the bus voltage climbs exponentially to twice the peak line voltage. If the bus voltage is greater than 200V, the doubler is not activated. In addition to providing transient/surge immunity and EMI filtering, the FARM contains all of the power switching and control circuitry necessary for autoranging rectification, inrush current limiting, and overvoltage protection. This module also provides converter enable and status functions for orderly power up/down control or sequencing. To complete the AC front end configuration, the user only needs to add hold-up capacitors, and a few discrete components. 3.1 If the bus voltage is greater than 235V as the slope approaches zero, the inrush limiting thermistor is bypassed. Below 235V, it is not bypassed. 4.1 The converters are enabled 50 milliseconds after the thermistor bypass switch is closed. 5.1 Bus-OK is asserted after an additional 50 millisecond delay to allow the converter outputs to settle within specification. Functional Description Power-Up Sequence. (see Fig. 8): 1.1 Upon application of input power, the output bus capacitors begin to charge. The thermistor limits the charge current, and the exponential time constant is determined by the hold-up capacitor value and the thermistor cold resistance. The slope (dv/dt) of the capacitor voltage versus time approaches zero as the capacitors become charged to the peak of the AC line voltage. Power-Down Sequence. (see Fig. 8) When input power is turned off or fails, the following sequence occurs as the bus voltage decays: 1.2 Bus-OK is deasserted when the bus voltage falls below 210Vdc. The switch that bypasses the inrush limiting PTC (positive temperature coefficient) thermistor is open when power is applied, as is the switch that engages the strap for voltage doubling. (see Fig. 7). In addition, the converter modules are disabled via the Enable (EN) line, and Bus-OK (BOK) is high. 2.2 The converters are disabled when the bus voltage falls below 190Vdc. If power is reapplied after the converters are disabled, the entire power-up sequence is repeated. If a momentary power interruption occurs and power is reestablished before the bus reaches the disable threshold, the power-up sequence is not repeated, i.e., the power conversion system “rides through” the momentary interruption.

The FARM automatically switches to the proper bridge or doubler mode depending on the input voltage, eliminating the possibility of damage due to improper line connection. The FARM1xxx is rated at 500W in the low range (90-132Vac input), and 750W in the high range (180-264Vac input). The FARM2xxx is rated for 750W and 1000W for the low and high input ranges respectively. Either of these modules can serve as the AC front end for any number and combination of compatible converters as long as the maximum power rating is not exceeded. Strap (ST) Pin. In addition to input and output power pin connections, it is necessary to connect the Strap pin to the center junction of the series hold-up capacitors (C1, C2, see Fig. 9) for proper (autoranging) operation. Gas tubes V1 and V2 provide capacitor protection. The bleeder resistors (R1, R2, see Fig. 9) discharge the hold-up capacitors when power is switched off. Capacitors C7 and C8 are recommended if the holdup capacitors are located more than 3 inches from the FARM output pins. Enable (EN) Pin. (see Fig. 10) The Enable pin must be connected to the PC or Gate-In pin of all converter modules to disable the converters during power-up. Otherwise, the converters would attempt to start while the hold-up capacitors were being charged through an unbypassed current limiting thermistor, preventing the bus voltage from reaching the thermistor bypass threshold, thus disabling the power supply. The Enable output (the drain of an N channel MOSFET) is internally pulled up to 15V through a 150kΩ resistor. A signal diode should be placed close to and in series with the PC or (Gate-In) pin of each converter to eliminate the possibility of control interference between converters. The Enable pin switches to the high state (15V) with respect to the negative output power pin to turn on the converters after the power-up inrush is over. The Enable function also provides input overvoltage protection for the converters by turning off the converters if the DC bus voltage exceeds 400Vdc. The thermistor bypass switch opens if this condition occurs, placing the thermistor in series with the input voltage, which reduces the bus voltage to a safe level while limiting input current in case the varistors conduct. The thermistor bypass switch also opens if a fault or overload reduces the bus voltage to less than 180Vdc.

A line isolation transformation should be used when performing scope measurements. Scope probes should never be applied simultaneously to the input and output as this will destroy the unit. Optocoupler DI pkg. 26106 Optocoupler SM pkg. 26109 Figure 11—Bus OK (BOK) isolated power status indicator Hold-up Capacitors. Hold-up capacitor values should be determined according to output bus voltage ripple, power fail hold-up time, and ride-through time (see Fig. 13). Many applications require the power supply to maintain output regulation during a momentary power failure of specified duration, i.e., the converters must hold-up or ride through such an event while maintaining undisturbed output voltage regulation. Similarly, many of these same systems require notification of an impending power failure in order to allow time to perform an orderly shutdown.

The Bus-OK and Enable thresholds are 205V and 185V, respectively. A simplified relationship between hold-up time, operating power, and bus capacitance is obtained by inserting these constants: 35 Power Fail Warning (ms) Ripple (V p-p) 1300µF 1600µF 1100µF 820µF 2200µF (FARM2XXX) 30 * 680µF 25 (FARM1XXX) 20 15 10 5 0 250 * * 500 1000 750 Operating Power (W) Figure 14—Hold-up time vs. operating power and total bus capacitance, series combination of C1, C2 (see Fig. 9) C = 2P∆t / (2052 – 1852) C = 2P∆t / (7,800) 100 Allowable ripple voltage on the bus (or ripple current in the capacitors) may define the capacitance requirement. Consideration should be given to converter ripple rejection and resulting output ripple voltage. The ripple rejection (R) of Vicor converters is specified as a function of the input/output voltage ratio: Where: (5) f = line frequency θ = rectifier conduction angle The approximate conduction angle is given by: ( ) θ = Cos-1 V2/V1 90Vac 115Vac 70 60 50 40 30 20 0 250 (4) For example, a converter whose output is 15V and nominal input is 300V will provide 56dB ripple rejection, i.e., 10V p-p of input ripple will produce 15mV p-p of output ripple (see Fig. 17). Equation 3 is again used to determine the required capacitance. In this case, V1 and V2 are the instantaneous values of bus voltage at the peaks and valleys (see Fig. 13) of the ripple, respectively.

Figure 15 illustrates ridethrough time as a function of line voltage and output power, and shows that at a nominal line of 90Vac, ride-through would be 68 ms. Ride-through time is a function of line voltage. 80 Ripple Rejection (dB) 75 70 Determining Ripple Voltage on the Hold-up Capacitors. Figure 16 is used to determine ripple voltage as a function of operating power and bus capacitance, and shows that the ripple voltage across the hold-up capacitors will be 12V p-p. 65 60 55 50 45 40 2 5 15 30 50 Output Voltage Figure 17—Converter ripple rejection vs. output voltage Another consideration in hold-up capacitor selection is their ripple current rating. The capacitors’ rating must be higher than the maximum operating ripple current. The approximate operating ripple current (rms) is given by: I rms = 2P/Vac (7) Where: P = total output power Vac = operating line voltage Determining the Ripple on the Output of the DC-DC Converter. Figure 17 is used to determine the ripple rejection of the DC-DC converter and indicates a ripple rejection of approximately 60 dB for a 12V output. Since the ripple on the bus voltage is 12Vac and the ripple rejection of the converter is 60 dB, the output ripple of the converter due to ripple on its input (primarily 120 Hz) will be 12mV p-p. Note that 2nd Generation converters have greater ripple rejection then either VI-200s or VI-J00s. For more information about designing an autoranging AC input power supply using the FARM and Vicor DC-DC converter modules, contact Vicor Applications Engineering at the nearest Vicor Technical Support Center, or send E-mail to [email protected]. ••• Calculated values of bus capacitance for various hold-up time, ride-through time, and ripple voltage requirements are given as a function of operating power level in Figures 14, 15, and 16, respectively. Example In this example, the output required from the DC-DC converter at the point of load is 12Vdc at 320W. Therefore, the output power from the FARM would be 375W (assuming a converter efficiency of 85%). The desired hold-up time is 9 ms over an input range of 90 to 264Vac. Determining Required Capacitance for Power Fail Warning. Figure 14 is used to determine capacitance for a given power fail warning time and power level, and shows that the total bus capacitance must be at least 820 µF. Since two capacitors are used in series, each capacitor must be at least 1,640 µF. Note that warning time is not dependent on line voltage.
