The ENMod system’s basic building blocks are the MiniHAM passive harmonic attenuation module, the FARM3 autoranging AC-DC front-end module (Figure 9) and a discrete EMI filter. The ENMod system provides transient/surge immunity, harmonic current attenuation and EMI filtering, in addition to all of the power switching and control circuitry necessary for autoranging rectification, inrush current limiting, and overvoltage protection. Converter enable and status functions for orderly power up/ down control or sequencing are also provided. To complete the AC front-end configuration, the user only needs to add hold-up capacitors, a simple EMI filter, and a few discrete components (see Figure 1a). Functional Description (FARM3, see Figures 9 & 10) 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. 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 ~150 milliseconds after the thermistor bypass switch is closed. 5.1 Bus-OK is asserted after an additional ~150 millisecond delay to allow the converter outputs to settle within specification. Power-Down Sequence: 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. Power-Up Sequence 1.1 Upon application of input power, the hold-up 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. 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 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. In addition, the converter modules are disabled via the Enable (EN) line, and Bus-OK (BOK) is high.

Bus-OK (BOK) Pin: (see Figure 12) The Bus-OK pin is intended to provide early-warning power fail information and is also referenced to the SR pin. Off-Line Power Supply Configuration The ENMod system maintains the DC output bus voltage between 250 and 370VDC over the entire input voltage range, which is compatible with all Vicor 300V input converters. Autoranging automatically switches to the proper bridge or doubler mode at startup depending on the input voltage, eliminating the possibility of damage due to improper line connection. The ENMod system is rated at 575W output power. 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. FARM3 Module Pin Descriptions (see Figures 1a, 18a and 18b) 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) for proper (autoranging) operation. Varistors V1 and V2 provide capacitor protection. The bleeder resistors (R1, R2) discharge the hold-up capacitors when power is switched off. Capacitors C7 and C8 are recommended if the hold-up capacitors are located more than 3 inches (75mm) from the output pins. CAUTION: There is no input to output isolation in the ENMods. 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. L, N Pins: Line and neutral input. +, – Pins: Positive and negative outputs. SR Pin: Signal return for BOK and EN outputs. MiniHAM Module Pin (see Figures 1a, 18a, and 18b) Filter (see Figure 1b) The input EMI filter consists of differential and common mode chokes, Y-rated capacitors (line-ground) and X-rated capacitors (line-line). This filter configuration provides 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, as illustrated in Figures 8a thru 8c. Enable (EN) Pin: 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 are being charged through the 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. (see Figure 11) 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 SR 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, reducing 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 (see Figure 9). CAUTION: There is no input to output isolation in the ENMods, hence the –Out of the ENMods and thus the –In of the downstream DC-DC converter(s) are at a high potential. If it is necessary to provide an external enable / disable function by controlling the DC-DC converter’s PC pin (referenced to the –In) of the converter an opto-isolator or isolated relay should be employed. ENMODS™ Page 8 of 13 Rev 3.3 06/2017 vicorpower.com 800 927.9474 EN1xxx Application Note (Cont.) Energy is given up by the capacitors as they are discharged by the converters. The energy expended (the power-time product) is: 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 Figure 15). Many applications require the power supply to maintain output regulation during a momentary power failure of specified duration, i.e., the converters must holdup 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. ε = 1/2(CV ) Where: Where: P = operating power Δt = discharge interval V1 = capacitor voltage at the beginning of Δt V2 = capacitor voltage at the end of Δt C = 2PΔt / (V12–V22) (1) (3) ε = stored energy C = capacitance V = voltage across the capacitor N SR L 15 Vdc 150 k Microcontroller Vicor DC-DC Converter 250 SR PR (Gate Out) EN L –In – Figure 11 — Enable (EN) function Secondary referenced ST EN Microcontroller – 100 1,600 µF 820 µF 90 2,200 µF * 680 µF Ride-through Time (ms) 1,300 µF 1,100 µF 30 25 20 15 10 * 5 500 Operating Power (W) Figure 13 — Power fail warning time vs. operating power and total bus capacitance, series combination of C1, C2 (see Figure 1a) ENMODS™ Page 9 of 13 27 k +5 Vdc BOK Figure 12 — Bus OK (BOK) isolated power status indicator 40 0 250 15 Vdc FARM3 FARM3 35 + EMI GND PC (Gate In) B OK ST N +In + EMI GND Power Fail Warning Time (ms) (2) Rearranging Equation 2 to solve for the required capacitance: The energy stored on a capacitor which has been charged to voltage V is: 2 ε = PΔt = C(V12–V22) / 2 Rev 3.3 06/2017 80 70 60 50 40 30 90 Vac 115 Vac 20 10 0 250 Operating Power (W) Figure 14 — Ride-through time vs. operating power vicorpower.com 800 927.9474 500 EN1xxx Application Note (Cont.)

Example The power fail warning time (∆t) is defined as the interval between BOK and converter shutdown (EN) as illustrated in Figure 15. The Bus-OK and Enable thresholds are 205V and 190V, respectively. A simplified relationship between power fail warning time, operating power, and bus capacitance is obtained by inserting these constants in Equation (3): C = 2PΔt / (2052 – 1902) C = 2PΔt / (5,925) It should be noted that the series combination (C1, C2, see Figure 1a) requires each capacitor to be twice the calculated value, but the required voltage rating of each capacitor is reduced to 200V. 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. 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 Figure 15) of the ripple, respectively. The capacitors must hold up the bus voltage for the time interval (∆t) between peaks of the rectified line as given by: Δt = (π – θ) / 2πf Where: (4) f = line frequency θ = rectifier conduction angle (5) 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: IRMS = 2P/Vac Where: (6) P = total output power 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 16, respectively. ENMODS™ Page 11 of 13 Determining Required Capacitance for Power Fail Warning: Figure 13 is used to determine capacitance for a given power fail warning time and power level, and shows that the total bus capacitance should be at least 820µF. Since two capacitors are used in series, each capacitor should be at least 1,640µF. Note that warning time is not dependent on line voltage. A hold-up capacitor calculator is available on the Vicor website, at: www.vicorpower.com/powerbench/product-calculators. Determining Ride-through Time: Figure 14 illustrates ride-through time as a function of line voltage and output power, and shows that at a nominal line of 90VAC, ride-through would be 68ms. Ride-through time is a function of line voltage. 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 12Vp-p. 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 60dB for a 12V output. Since the ripple on the bus voltage is 12VAC and the ripple rejection of the converter is 60dB, the output ripple of the converter due to ripple on its input (primarily 120Hz) will be 12mVp-p. A variety of hold-up capacitor assemblies (HUBs) are available. Please visit the Vicor website at: www.vicorpower.com/powerbench/product-calculators. The approximate conduction angle is given by: θ = Cos-1V2 /V1 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 ENMods would be 375W (assuming a converter efficiency of 85%). The desired hold-up time is 9ms over an input range of 90 to 264VAC.
