Product Overview
The VI Brick® AC Front End is an AC-to-DC converter, operating
from a universal AC input to generate an isolated and regulated
48 Vdc output with power factor correction. The module
incorporates rectification, transient and surge suppression and
AC to DC conversion to provide a complete AC to DC solution in
a thin profile package. With its ZVS high frequency Adaptive
CellTM topology, the VI Brick AC Front End module consistently
delivers high efficiency across worldwide AC mains.
Downstream DC-DC converters support secondary-side energy
storage and efficient power distribution, providing superior
power system performance and connectivity from the wall plug
to the point-of-load.

Holdup Capacitor
Figure 26 – 300 W Universal AC-to-DC Supply
VI Brick products are not internally fused in order to provide flexibility
in configuring power systems. Input line fusing is recommended at
system level, in order to provide thermal protection in case of
catastrophic failure. The fuse shall be selected by closely matching
system requirements with the following characteristics:
The VI Brick® AC Front End is a high efficiency AC-to-DC converter,
operating from a universal AC input to generate an isolated SELV 48
VDC output bus with power factor correction. It is the key component
of an AC-to-DC power supply system such as the one shown in Figure
26 above.
 Recommended fuse: 5 A, 216 Series Littelfuse
 Current rating
The input to the VI Brick AC Front End is a sinusoidal AC source with a
power factor maintained by the module with harmonics conforming to
IEC 61000-3-2. Internal filtering enables compliance with the standards
relevant to the application (Surge, EMI, etc.). See EMI/EMC Compliance
standards on page 13.
 Ambient temperature
 Breaking capacity per application requirements
 Nominal melting I2t
The module uses secondary-side energy storage (at the SELV
48 V bus) and optional PRM® regulators to maintain output hold up
through line dropouts and brownouts. Downstream regulators also
provide tighter voltage regulation, if required.
The FE175D480C033FP-00 is designed for standalone operation;
however, it may be part of a system that is paralleled by downstream
DC-DC converters. Contact Vicor Sales or refer to our website,
www.vicorpower.com, regarding new models that can be paralleled
directly for higher power applications.

Fault Handling
Input Undervoltage (UV) Fault Protection
The VI Brick AC Front End’s input voltage (proportional to VIN-B as
shown on page 6) is monitored by the micro-controller to detect an
input under voltage condition. When the input voltage is less than the
VIN-UVLO-, a fault is detected, the fault latch and reset logic disables the
modulator, the modulator stops powertrain switching, and the output
voltage of the unit falls. After a time tUVLO, the unit shuts down. Faults
lasting less than tUVLO may not be detected. Such a fault does not go
through an auto-restart cycle. Once the input voltage rises above VINUVLO+, the unit recovers from the input UV fault, the powertrain
resumes normal switching after a time tON and the output voltage of
the unit reaches the set-point voltage within a time tSS.
Overcurrent (OC) Fault Protection
Isolated
DC / DC 12 V Bus
Converter
Figure 27 – Traditional PFC AC-to-DC supply
To cope with input voltages across worldwide AC mains
(85 – 264 Vac), traditional AC-DC power supplies (Figure 27)
use two power conversion stages: 1) a PFC boost stage to step up from a
rectified input as low as 85 Vac to ~380 Vdc; and 2) a DC-DC down
converter from 380 Vdc to a 12 V bus.
The efficiency of the boost stage and of traditional power supplies is
significantly compromised operating from worldwide AC lines as low
as 85 Vac.
Adaptive Cell™ Topology
With its single stage Adaptive Cell™ topology, the VI Brick AC Front
The unit’s output current, determined by VEAO, VIN_B and the primaryside sensed output voltage, (as shown on page 6) is monitored by the
microcontroller to detect an output OC condition. If the output current
exceeds its current limit, a fault is detected, the reset logic disables the
modulator, the modulator stops powertrain switching, and the output
voltage of the module falls after a time tOC. As long as the fault persists,
the module goes through an auto-restart cycle with off time equal to
tOFF + tON and on time equal to tOC. Faults shorter than a time tOC may
not be detected. Once the fault is cleared, the module follows its normal
start up sequence after a time tOFF.
Short Circuit (SC) Fault Protection
The microcontroller determines a short circuit on the output of the unit
by measuring its primary sensed output voltage and EAO (as shown on
page 6). Most commonly, a drop in the primary-sensed output voltage
triggers a short circuit event. The module responds to a short circuit
event within a time tSC. The module then goes through an auto restart
cycle, with an off time equal to tOFF + tON and an on time equal to tSC,
for as long as the short circuit fault condition persists. Once the fault is
cleared, the unit follows its normal start up sequence after a time tOFF.
Faults shorter than a time tSC may not be detected.

Temperature Fault Protection
The output voltage has the following two components of voltage ripple:
The microcontroller monitors the temperature within the
VI Brick® AC Front End. If this temperature exceeds TJ-OTP+,
an overtemperature fault is detected, the reset logic block disables the
modulator, the modulator stops the powertrain switching and the
output voltage of the VI Brick AC Front End falls. Once the case
temperature falls below TCASE-OTP-, after a time greater than or equal to
tOFF, the converter recovers and undergoes a normal restart. For the Cgrade version of the converter, this temperature is 75°C. Faults shorter
than a time tOTP may not be detected. If the temperature falls below
TCASE-UTP-, an undertemperature fault is detected, the reset logic
disables the modulator, the modulator stops powertrain switching and
the output voltage of the unit falls. Once the case temperature rises
above TCASE-UTP, after a time greater than or equal to tOFF, the unit
recovers and undergoes a normal restart.

The microcontroller monitors the primary sensed output voltage (as
shown on page 6) to detect output OVP. If the primary sensed output
voltage exceeds VOUT-OVLO+, a fault is latched, the logic disables the
modulator, the modulator stops powertrain switching, and the output
voltage of the module falls after a time tSOVP. Faults shorter than a time
tSOVP may not be detected. This type of fault is a latched fault and
requires that 1) the EN pin be toggled or 2) the input power be recycled
to recover from the fault.
Hold-up Capacitance
The VI Brick AC Front End uses secondary-side energy storage (at the
SELV 48 V bus) and optional PRM® regulators to maintain output hold
up through line dropouts and brownouts. The module’s output bulk
capacitance can be sized to achieve the required hold up functionality.
Hold-up time depends upon the output power drawn from the VI Brick
AC Front End based AC-to-DC front end and the input voltage range of
downstream DC-to-DC converters.

EMI Filtering and Transient Voltage Suppression
EMI Filtering
The VI Brick AC® Front End with PFC is designed such that it will
comply with EN55022 Class B for Conducted Emissions with the filter
connected across -IN and GND as shown in Figure 28. The emissions
spectrum is shown in Figures 13-16. If one of the outputs is connected
to earth ground, a small (single turn) output common mode choke is
also required.
EMI performance is subject to a wide variety of external influences
such as PCB construction, circuit layout etc. As such, external
components in addition to those listed herein may be required in
specific instances to gain full compliance to the standards specified.
Transient Voltage Suppression
The VI Brick AC Front End contains line transient suppression circuitry
to meet specifications for surge (i.e. EN61000-4-5) and fast transient
conditions (i.e. EN61000-4-4 fast transient/“burst”).
Thermal Design
In certain applications, the choice of bulk capacitance may be
determined by hold-up requirements and low frequency output
voltage filtering requirements. Such applications may use the greater
capacitance value determined from these requirements. The ripple
current rating for the bulk capacitors can be determined from the
following equation:
Iripple
Thermal management of internally dissipated heat should maximize
heat removed from the baseplate surface, since the baseplate represents
the lowest aggregate thermal impedance to internal components. The
baseplate temperature should be maintained below 100°C. Cooling of
the system PCB should be provided to keep the leads below 100°C, and
to control maximum PCB temperatures in the area of the module.
Powering a Constant Power Load
~
=
0.8 * POUT / VOUT
Switching Frequency Filtering
Some applications require the output filtering shown in figure 28 to
meet radiated emissions limits. In such a situation, the output
switching ripple shown in figure 6 should be expected at the output of
the filter. In cases where other means are used to control radiated
emissions, and more ripple can be tolerated, the output filter can be
simplified by removal of the common mode inductor, and C5, which is
used to reduce the Q of the LC resonant tank.
Output switching frequency voltage ripple is the function of the output
bypass ceramic capacitor. Output bypass ceramic capacitor values
should be calculated based on switching frequency voltage ripple.
Normally bypass capacitors with low ESR are used with a sufficient
voltage rating.
Output bypass ceramic capacitor value for allowable peak-to-peak
switching frequency voltage ripple can be determined by:
C3 = QTOT / VOUT-PP-HF – COUT-INT
where:
VOUT-PP-HF
Allowable peak-to-peak output switching

COUT_INT

C3
Required output bypass ceramic capacitor
When the output voltage of the VI Brick AC Front End module is
applied to the input of the PRM® regulator, the regulator turns on and
acts as a constant-power load. When the module’s output voltage
reaches the input undervoltage turn on of the regulator, the regulator
will attempt to start. However, the current demand of the PRM®
regulator at the undervoltage turn-on point and the hold-up capacitor
charging current may force the VI Brick AC Front End into current
limit. In this case, the unit may shut down and restart repeatedly. In
order to prevent this multiple restart scenario, it is necessary to delay
enabling a constant-power load when powered up by the upstream AC
to 48 V front end until after the output set point of the VI Brick AC
Front End is reached.
This can be achieved by
1) keeping the downstream constant-power load
off during power up sequence
and
2) turning the downstream constant-power load
on after the output voltage of the module
reaches 48 V steady state.
After the initial startup, the output of the VI Brick AC Front End can be
allowed to fall to 30 V during a line dropout at full load. In this case, the
circuit should not disable the PRM regulator if the input voltage falls
after it is turned on; therefore, some form of hysteresis or latching is
needed on the enable signal for the constant power load. The output
capacitance of the VI Brick AC Front End should also be sized
appropriately for a constant power load to prevent collapse of the
output voltage of the module during line dropout (see Hold up
Capacitance on page 17). A constant-power load can be turned off after
completion of the required hold up time during the power-down
sequence or can be allowed to turn off when it reaches its own
undervoltage shutdown point.

Product Details and Design Guidelines (cont.)
The timing diagram in Figure 30 shows the output voltage of the VI
Brick® AC Front End module and the PRM® PC pin voltage and output
voltage of the PRM regulator for the power up and power down
sequence. It is recommended to keep the time delay approximately 10
to 20 ms.

Special care should be taken when enabling the constant-power load
near the auto-ranger threshold, especially with an inductive source
upstream of the VI Brick AC Front End. A load current spike may cause
a large input voltage transient, resulting in a range change which could
temporarily reduce the available power (see Adaptive Cell™ Topology
below).
Adaptive Cell™ Topology
The Adaptive Cell topology utilizes magnetically coupled “top” and
“bottom” primary cells that are adaptively configured in series or
parallel by a configuration controller comprised of an array of switches.
A microcontroller monitors operating conditions and defines the
configuration of the top and bottom cells through a range control
signal.
Source Inductance Considerations
The AC Front End Powertrain uses a unique Adaptive Cell Topology
that dynamically matches the powertrain architecture to the AC line
voltage. In addition the AC Front End uses a unique control algorithm
to reduce the AC line harmonics yet still achieve rapid response to
dynamic load conditions presented to it at the DC output terminals.
Given these unique power processing features, the AC Front End can
expose deficiencies in the AC line source impedance that may result in
unstable operation if ignored.
It is recommended that for a single AC Front End, the line source
inductance should be no greater than 1 mH for a universal AC input of
100 - 240 V. If the AC Front End will be operated at 240 V nominal only,
the source impedance may be increased to 2 mH. For either of the
preceding operating conditions it is best to be conservative and stay
below the maximum source inductance values. When multiple AC
Front End’s are used on a single AC line, the inductance should be no
greater than 1 mH/N, where N is the number of AC Front End’s on the
AC branch circuit, or 2 mH/N for 240 Vac operation. It is important to
consider all potential sources of series inductance including and not
limited to, AC power distribution transformers, structure wiring
inductance, AC line reactors, and additional line filters. Non-linear
behavior of power distribution devices ahead of the AC Front End may
further reduce the maximum inductance and require testing to ensure
optimal performance.
If the AC Front End is to be utilized in large arrays, the AC Front Ends
should be spread across multiple phases or sources thereby minimizing
the source inductance requirements, or be operated at a line voltage
close to 240 Vac. Vicor Applications should be contacted to assist in the
review of the application when multiple devices are to be used
in arrays.
A comparator inside the microcontroller monitors the line voltage and
compares it to an internal voltage reference.
If the input voltage of the VI Brick AC Front End crosses above the
positive going cell reconfiguration threshold voltage, the output of the
comparator transitions, causing switches S1 and S2 to open and switch
S3 to close (see Functional Block Diagram on page 6). With the top cell
and bottom cell configured in series, the unit operates in “high” range
and input capacitances CIN-T and CIN-B are in series.
If the peak of input voltage of the unit falls below the negative-going
range threshold voltage for two line cycles, the cell configuration
controller opens switch S3 and closes switches S1 and S2. With the top
cell and bottom cells configured in parallel, the unit operates in “low”
range and input capacitances CIN-T and CIN-B are in parallel.
Power processing is held off while transitioning between ranges and
the output voltage of the unit may temporarily droop. External output
hold up capacitance should be sized to support power delivery to the
load during cell reconfiguration. The minimum specified external
output capacitance of 6,000 μF is sufficient to provide adequate ridethrough during cell reconfiguration for typical applications.
