Technical Description
The Badger II consists of an off-line single phase, power-factor-corrected front end, EMI filter, cooling fan,
customer interface, associated housekeeping circuits, and a selection of Vicor’s DC-DC converters.
Input AC mains voltage is applied to a 3-pin power connector. The input current is passed through an EMI
filter to meet conducted noise limits.

Badger II Power Supply Operator’s Manual
Rev. 05/11/2012 Mission Power Solutions [phone] [email protected] Pg. 6
At start-up, inrush current is limited by a PTC thermistor. The PTC is shunted out shortly after initial power-up
by a DC bus voltage sense circuit driving a thyristor. After rectification, the input voltage is put through a boost
converter that keeps the AC input current sinusoidal and synchronized with the input AC voltage. The boost
converter delivers a regulated input to the hold-up capacitors and a high voltage backplane. The backplane sup-
plies power to the DC-DC converters that provide the desired low voltage, regulated outputs.
Voltage conversion is achieved by Vicor’s family of Zero-Current-Switching (ZCS) DC-DC converters. These
are forward converters in which the main switching element switches at zero current. This patented topology
has a number of unique attributes: low switching losses, high frequency operation (resulting in reduced size for
magnetics and capacitors), excellent line and load regulation, wide output adjustment range, low EMI/RFI
emission, and high efficiency.
At initial power-up, the Badger II outputs are disabled to limit the inrush current and to allow the DC bus po-
tential to settle out to the correct operating level. A low-power flyback converter operating with PWM current-
mode control converts the high voltage DC bus into regulated low voltage to power the internal housekeeping
circuits and DC cooling fans.
The internal housekeeping Vcc comes up within 1 second after the application of input power. Once the high
voltage bus is within operating limits, the AC Power OK signal changes its output to a TTL “1,” indicating the
input power is OK, and allows the power outputs to come up 15-30 ms later. An auxiliary Vcc output of 5 VDC
capable of sourcing up to 0.1 A is provided for peripheral use.
An output Enable/Disable function is provided by using an optocoupler to control Vicor’s DC-DC converters.
If the Enable/Disable control pin is pulled low, the optocoupler turns on and disables the output. The delay for
an output to come up when measured from release of the Enable/Disable pin is 5-10 ms. The General Shut-
down function controls all outputs simultaneously and works in a similar manner.

Interface Connections
Input Terminal (J1)
Input AC Power is applied to connector J1 using a 3W3 power connector. J1-A1 is Line (L1), J1-A2 is Line 2/
Neutral (L2/N) and J1-A3 is Earth Ground (GND) for safety. See Figure 8 (Pg 4).
A fault clearing device, such as a fuse or circuit breaker, with a maximum 15 A rating at the power supply input
is recommended. It should be sized to handle the start-up inrush of 30 A at 115 VAC and 60 A at 230 VAC.
Customer Interface Connector (J2)
Individual outputs for slots 1 through 3 can be disabled with a logic “0” at pins 1, 2 and 3 of J2. Signal Ground
is available at pin 4. Auxiliary +5 Vcc @ 100 mA is available at pin 5. The AC Power OK at pin 6 is a logic
“1” whenever AC input power is within tolerance. All outputs can be disabled by placing pin 7 at a logic “0” by
connecting to signal ground at pin 4. Pins 8 and 9 are not used. See Figure 9 (Pg 4).
Signal Ground (J2-4)
Signal Ground on J2-4 is an isolated secondary ground reference for all J2 interfacing signals. This is not the
same as Earth Ground on input power connector J1.
Enable/Disable (J2-1 to J2-3)
The Enable/Disable control pins allow outputs to be sequenced either on or off. J2-1 through J2-3 are the con-
trol pins for output cards 1 through 3, respectively. For dual or quad output cards, all outputs in that slot are
enabled or disabled with a single control. The Enable/Disable pins should be pulled low to less than 0.7 V with
respect to Signal Ground to disable the outputs. They will source 4 mA maximum. These pins should be open-
circuited or allowed to exceed 4.5 V when enabled. Do not apply more than 5 V to these inputs at any time.

General Shutdown (J2-7)
The General Shutdown (GSD) control pin on J2-7 allows simultaneous shutdown of all outputs. This pin must
be pulled down to less than 0.7 V and will source 4 mA maximum to shut down all outputs. The GSD pin
should be open-circuited or allowed to exceed 4.5 V when not in use, or when the outputs are to be enabled.
Do not apply more than 5V to this input at any time. Normal open-circuit voltage is 1.5-3 V with respect to
Signal Ground.
AC OK (J2-6)
AC OK is an active high TTL-compatible signal and provides a status indication of the AC input power. It is
on pin J2-6 and is capable of sinking 16 mA maximum. This signal switches to a TTL “1” when the high volt-
age bus exceeds low-line condition during turn-on. Upon loss of input power, the bus voltage will drop, caus-
ing the AC OK signal to go low. A minimum of 3 ms holdup time is provided for a 1,200 W load following
the loss of the AC OK signal.

Output/Customer Interface Connections
Figure 14. Output Connections for Single Output Cards
There are three types of output power terminals available in the Badger II. Outputs from Maxi converters
(single output cards) are terminated in two 10-32 stainless steel studs (see Fig. 14). The positive polarity of the
output is the right stud when viewed from the output end. Outputs from Mini converters (dual output cards)
terminate in a 7W2 connector (see Fig.15). Each power output is isolated, so outputs of positive or negative
polarity can be configured through proper selection of the output reference terminals. Outputs from three or
four Micro converters (quad output cards) terminate in a 16-pin Positronics connector (see Fig. 16).
In order to minimize parasitic cable inductance and reduce EMI, the output power cables should be routed in
close proximity to one another, and large current loops should be avoided. To avoid excessive voltage drop, do
not undersize power cables, especially for high current outputs. Excessive cable inductance, coupled with large
capacitive loading, can introduce instability in switching power supplies. This problem can be avoided with
proper system design. Consult Mission Power Solutions’ Engineering Department for assistance with applica-
tions that use long cable lengths and excessive load capacitance.

Sense Connections
The Badger II is shipped from the factory with Local Sense installed. If Remote Sense is desired, the Local
Sense jumpers can be removed for individual outputs. If the Local Sense jumpers are removed, the sense lines
must be connected at the load for Remote Sense. Leaving the sense lines open will prevent proper output
regulation and can result in damage to the unit.
When Local Sense is used, the power supply will regulate the output at the output terminals. The voltage ap-
pearing at the load may drop slightly due to voltage drop in the power cables. If it is necessary to compensate
for voltage drop along the output power cables, the output can be trimmed up or configured for Remote Sense.
Use stranded twisted pair 22-24 AWG wire for the Remote Sense lines. Remote Sense can compensate for a
voltage drop of up to 0.5 V, or 0.25 V on each leg.
Output Connections
Figure 16. Output Connections for Quad Output Cards

Badger II Power Supply Operator’s Manual
Installing Remote Sense requires the Local Sense jumpers to be removed (see Figures 4 and 5, Pg 3). On single
output cards, the Local Sense jumpers are located behind the sense connector on JMP1 and JMP2. To remove the
jumpers, make certain the power to the supply is off, and pull them off connectors JMP1 and JMP2. On dual out-
put cards, the Local Sense jumpers are on either side of the card at JMP1and JMP2 for Output 1, and at JMP3
and JMP4 for Output 2.
The sense connector for a single output card is a 3-pin connector providing the +Sense connection on J3-1 and
the –Sense connection on J3-3. The sense connections for a dual output card are incorporated into the 7W2 D-
shell connector(s) that also provide the output and trim connection(s). +Sense is pin 3 of each connector,
and -Sense is pin 5 of each connector.

External Trim
The trim pin at J3-2 (single output) or J3-4, J4-4 (dual output) is referenced to the -Sense pin and can be used
for external control of the output voltage. A 10% increase to the trim pin voltage will result in a 10% increase
in output voltage. Reducing the trim pin voltage by 10% will result in a 10% decrease in output voltage.
Note: Converters are sometimes pre-trimmed at the factory if a nonstandard output voltage is requested. If a
non-standard voltage is requested, or when trimming below 5 V, consult Mission Power for assistance.

Example: 10% trim adjust on a 12 V nominal output.
Figure 18 shows a typical variable trim circuit. Using a 1k trimpot (R7), the resistor values for R6 and R8 can
be calculated as follows:
V1 =Vref + 10% = 1.353V
Given: Vref = 1.23V
IR5 = (1.353V - Vref)/RTH = (1.353V –1.23V)/1k= 122A Given: RTH = 1k
Setting the bottom limit:
VR6 = 1.23V –10% = 1.107V
And since IR5 = IR6 = 122A,
R6 = VR6/IR6 = 1.107V/122A = 9.074k
V2= V1+ VR6 = 1.353V + 1.107V =2.46V
IR7 = V2/R7 = 2.46V/1k= 2.46mA
IR8 = IR7 + IR6 = 2.58mA
VR8 = (Vnom + 10%) –V2= 13.2V –2.46V = 10.74V Given: Vnom = 12V
R8 = VR8/IR8 = 10.74V/2.58mA = 4.162k

Mechanical Considerations
The Badger II can be mounted on either of two surfaces using standard 8-32 size screws. Maximum allowable
torque is 20 in/lbs., and the maximum penetration is 0.18 in. (4.5 mm).
When selecting a mounting location and orientation, the unit should be positioned so airflow is not restricted.
Maintain a 2″ (50,8 mm) minimum clearance at both ends of the Badger II, and route all cables so airflow is not
obstructed. The power supply draws air in at the fan/AC input side and exhausts air out the load side. If airflow
ducting is used, avoid sharp turns that could create back pressure. The fans move approximately 75 CFM of air.
Avoid excessive bending of output power cables after they are connected to the output terminals. For high-
current outputs, use cable ties to support heavy cables and minimize mechanical stress on connectors. Be care-
ful not to short out to neighboring outputs. The maximum torque recommended on output nuts is 10 in/lbs.
Badger II Do’s and Don’ts
 Run the output (+/) power cables next to each other to minimize inductance.
 Insert proper fault protection at power supply input terminals (i.e., a fuse).
 Use proper size wires to avoid overheating and excessive voltage drop.
 Do not attempt to repair or modify the power supply in any manner.
 Do not restrict airflow to the unit. The cooling fan draws air into the unit and forces it out at the output
power terminals.
 If sense jumpers are removed, do not leave sense lines open. Use twisted pair 22-24 AWG wire when
installing Remote Sense.
