Product Highlights The ARM (Autoranging Rectifier Module) is an AC front end module which provides autoranging line rectification and inrush current limiting. The ARM is available in either 500/750W or 750/1000W models in a mini sized package measuring only 2.28" x 1.45" x 0.5". The ARM interfaces directly with worldwide AC mains and may be used with Vicor 1st or 2nd Generation 300V input DC-DC converters to realize an autoranging, high density, low profile switching power supply. The ARM includes a microcontroller that continuously monitors the AC line to control bridge/doubler operation. The user need only provide external capacitance to satisfy system hold-up requirements. Vicor 2nd Generation packaging technology offers flexible mounting options for various manufacturing processes. The ARM may be installed as a conventional leaded device for on-board applications, in-board for low profile, height restricted applications, socketed or surface mounted with optional ModuMate interconnect products.

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. The ARM 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 needs only to add holdup capacitors and a suitable input filter with transient protection. 3.1 If the bus voltage is greater than 235V as the slope approaches zero, the inrush limiting thermistor is bypassed. Below 235V, the thermistor 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 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. 6). In addition, the converter modules are disabled via the Enable (EN) line, and Bus-OK (B OK) is high. Power-Down Sequence. (See Fig. 7). 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 205Vdc (Typ.). 2.2 The converters are disabled when the bus voltage falls below 200Vdc. 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. Power-Up Sequence. (See Fig. 7).: 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 holdup capacitor value and the thermistor cold resistance. The slope (dv/dt) of the capacitor voltage approaches zero as the capacitors become charged to the peak of the AC line voltage. 1.1 Power Up +Out Power Down 90–132V AC Line PTC Thermistor Strap L Strap Output Bus (Vdc) –Out N EN Microcontroller BOK 400 300 200 100 0 1.1 2.1 Strap PTC Thermistor Bypass Converter Enable Bus OK 3.1 50ms 4.1 50ms Figure 6—Functional block diagram Vicor Corp.

(See Fig. 9). The Enable pin must be connected to the Gate-In or PC pin of all converter modules to disable the converters during power-up. Otherwise, the converters would attempt to start while the holdup capacitors were being charged through an unbypassed 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. The ARM maintains the DC output bus voltage between 200 and 375Vdc over the entire universal input range, which is compatible with Vicor VI-260 series and VI-J60 series DC-DC converters, as well as next-generation 300V input Vicor converters. The ARM automatically switches to the proper rectification mode (doubled or undoubled) depending on the input voltage, eliminating the possibility of damage due to improper line connection. The ARM–1 is rated at 500W in the low range (90-132Vac input), and 750W in the high range (180-264Vac input). The ARM–2 is rated for 1000W and 1500W 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. A signal diode should be placed close to and in series with the 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 gas tubes fire. The thermistor bypass switch also opens if a fault or overload reduces the bus voltage to less than 180Vdc. Strap (ST) Pin. In addition to input and output power pin connections, it is necessary to connect the Strap pin to the junction of the series holdup capacitors (C1, C2, Fig. 8) for proper (autoranging) operation. Gas tubes across the capacitors provide input transient protection. The bleeder resistors (R1, R2, Fig. 8) discharge the holdup capacitors when power is switched off.

It is necessary to monitor Bus-OK via an optoisolator if it is to be used on the secondary (output) side of the converters. A line isolation transformer 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. Filter. Two input filter recommendations are shown for low power VI-ARM-1 and high power VI-ARM-2 (See Fig. 11). Both filter configurations provide sufficient common mode and differential mode insertion loss in the frequency range between 100kHz and 30MHz to comply with the Level B conducted emissions limit. 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. 12). 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.

(See Fig. 16) 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. 12) of the ripple, respectively.

Fig. 15 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 12Vac. 80 Ripple Rejection (dB) 75 70 Determining the Ripple on the Output of the DC-DC Converter. Fig. 16 is used to determine the ripple rejection of the DC-DC converter and indicates a ripple rejection of approximately 60 dB for a 12 Volt output. If 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 120Hz) will be 12 mV p-p.

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 Where: For more information about designing an autoranging AC input power supply using the ARM and Vicor DC-DC converter modules, contact Vicor Applications Engineering at the nearest Vicor Technical Support Center (see back cover), or send an E-mail to [email protected]. ••• (7) P = operating power level Vac = operating line voltage 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 13, 14, and 15, respectively. Example In this example, the output required at the point of load is 12Vdc at 320 Watts. Therefore, the output power from the ARM would be 375 Watts (assuming a converter efficiency of 85%). The desired hold-up time is 9 ms over an input range of 90 to 264Vac. Determining Required Hold-up Capacitance. Fig. 13 is used to determine hold-up capacitance for a given hold-up time and power level, and shows that the total bus capacitance must be at least 820µF. Since two capacitors are used in series, each capacitor must be at least 1,640µF. Note that hold-up time is not dependent on line voltage. Determining Ride-through Time. Figure 14 illustrates ridethrough time as a function of line voltage and output power, and shows that at a nominal line of 115Vac, ride-through would be 68 ms. Ride-through time is a function of line voltage. Vicor Corp.
