Front End System
for EN Compliance

57,9 x 55,9 x 12,7 mm
Product Highlights
The ENMods system is a new AC front end
solution for compliance to electromagnetic
compatibility (EMC) standards. It consists of
the MiniHAM — a passive harmonic
attenuation module and the FARM3 — an
auto ranging AC-DC front end module.
Combined with the filtering and hold-up
capacitors as specified herein, the ENMods
system provides full compliance to:
EN61000-3-2 Harmonic Current
EN55022, Level B Conducted Emissions
EN61000-4-5 Surge Immunity
EN61000-4-11 Line Disturbances
The MiniHAM is the first passive product
specifically designed for compliance to EN
harmonic current limits. Unlike active PFC
solutions, the MiniHAM generates no EMI,
greatly simplifying and reducing system
noise filtering requirements. It is also
considerably smaller and more efficient than
active alternatives and improves MTBF by
an order of magnitude. Optimized for
operation on the DC bus (provided by the
FARM3) rather than directly on the AC line,
it will provide harmonic current compliance
up to 600W of input power at 230Vac.
The 115/230Vac input FARM3 is a new
member of Vicor’s Filter and Autoranging
Module product line that has been optimized
for use as the front end for the MiniHAM.
Both modules are in Vicor’s standard Mini
half-brick package. Together with Vicor’s
1st or 2nd Generation 300V input DC-DC
converters, they form the basis of a low
noise, high efficiency, rugged, simple and
reliable EN compliant power system.

Application Note
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 ENMods system provides an effective solution for the AC
front end of a power supply built with Vicor DC-DC converters.
This high performance power system building block satisfies a
broad spectrum of requirements and agency standards.
The ENMods 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 (Fig 1A).
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.
Functional Description (FARM3, see Figures 9 & 10)
5.1 Bus-OK is asserted after an additional 50 millisecond
delay to allow the converter outputs to settle within
specification.
Power-Up Sequence.
Power-Down Sequence. When input power is turned off or
fails, the following sequence occurs as the bus voltage decays:
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.
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. 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.

Application Note (continued)
Off-Line Power Supply Configuration
The ENMods 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 ENMods 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.
Pin Descriptions (see Figure 1a)
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 from the output pins.
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, 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. (see Figure 9)
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.
L, N Pins. Line and neutral input.
+, – Pins. Positive and negative outputs.
SR Pin. Signal return for BOK and EN outputs
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.
Hold-up Capacitors
Hold-up capacitor values should be determined according to
output bus voltage ripple, power fail hold-up time, and ridethrough time (see Figure 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 energy stored on a capacitor which has been charged to
voltage V is:
Where:
ε = 1/2(CV2)
ε = stored energy
(1)
C = capacitance
V = voltage across the capacitor
Energy is given up by the capacitors as they are discharged by
the converters. The energy expended (the power-time product) is:
ε = P∆t = C(V12–V22) / 2
Where:
(2)
P = operating power
∆t = discharge interval
V1 = capacitor voltage at the beginning of ∆t
V2 = capacitor voltage at the end of ∆t
Rearranging Equation 2 to solve for the required
capacitance:
C = 2P∆t / (V12–V22)
(3)
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.

PRELIMINARY
Application Note (continued)
The power fail warning time (∆t) is defined as the interval
between BOK and converter shutdown (EN) as illustrated in
Figure 13. 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 in equation (3):
2
2
C = 2P∆t / (205 – 185 )
C = 2P∆t / (7,800)
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:

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 Figure 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 Figure 13) of the ripple, respectively. The capacitors
must holdup the bus voltage for the time interval (∆t) between
peaks of the rectified line as given by:
∆t = (π – θ) / 2πf
Where:

f = line frequency
θ = rectifier conduction angle
The approximate conduction angle is given by:
(
)
θ = Cos-1 V2/V1
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 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 vicorpower.com.
Determining Ride-through Time. 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 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 12V p-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 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.
(6)
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
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 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.
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.
R = 30 + 20log(Vin / Vout)
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.
