DESCRIPTION
The PWR-82331 and PWR-82333 are 30 A, 3-phase motor drive
hybrids. The PWR-82331 has a +200 V rating and uses MOSFETs in
the output stage while the PWR-82333 has a +500 V rating and an IGBT
output stage. Both types have individual fast recovery diodes internally
connected across the output drive transistors to clamp inductive flyback.
These Smart Power Motor Drives have CMOS Schmitt Trigger inputs for
high noise immunity. High- and low-side input logic signals are XOR’d
in each phase to prevent simultaneous turn-on of in-line transistors, thus
eliminating a shoot through condition. The internal logic controls the
high- and low-side gate drives for each phase and can operate from +5
to +15 V logic levels. The internal power supply provides a constant volt-
age source to the floating high-side gate drives, and constant output per-
formance for switching frequencies from dc to 50 kHz.
APPLICATIONS
These hybrids are an excellent choice for high-performance, high-reli-
ability motor drives for Military and Aerospace servo-amps and speed
controls. Among the many applications are robotics; electro-mechan-
ical valve assemblies; actuator systems for flight control surfaces on
military and commercial aircraft; antenna and radar positioning; fan
and blower motors for environmental conditioning; thrust and vector
position control of mini-subs, drones, and RPV’s; compressor motors
for cryogenic coolers; and high power inverters.
The PWR-82331/82333 hybrids are ideal for harsh military environments
where shock, vibration, and temperature extremes are evident, such as
missile applications where fin actuator systems control missile direction.

INTRODUCTION
The 3-phase PWR-82331 and PWR-82333 are 30 A motor drive
hybrids rated at +200 V and +500 V respectively. The PWR-
82331 uses a MOSFET output stage and the PWR-82333 has
an IGBT output stage for high speed, high current, and high effi-
ciency operation. The PWR-82333 also offers high-voltage per-
formance of an IGBT for use in +270 V systems. These motor
drives are ideal for use in high-performance motion control sys-
tems, servo amplifiers, and motor speed control designs.
Furthermore, multi-axis systems requiring multiple drive stages
can benefit from the small size of these power drives.
The PWR-82331/33 can be driven directly from the commutation
logic, DSP, or a custom ASIC that supplies digital signals to con-
trol the upper and lower transistors of each phase. These high-
ly integrated drive stages have Schmitt trigger digital inputs
that control the high and low side of each phase. Digital protec-
tion of each phase eliminates an in-line firing condition by pre-
venting simultaneous turn-on of both the upper and lower tran-
sistors. The logic controls the high- and low-side gate drivers.
Operation from +5 to +15 V logic levels can be programmed by
applying the appropriate voltage to pin 16 (VLPI). The PWR-
82331/333 has a ground referenced low-side gate drive. An
internal dc-dc converter supplies a floating output to each side of
the three high-side drives. This provides a continuous high-side
gate drive even during the motor stall. Pin 15 (VLPO) supplies a
+15 V output, which can be used to power the internal logic when
system usage requires +15 V logic. The high- and low-side gate
drivers control the N-channel MOSFET or IGBT output stage.
The MOSFETs used in the PWR-82331 allow output switching
up to 50 kHz, while the high-speed IGBTs in the PWR-82333 can
switch at 25 kHz. A flyback diode parallels each output transis-
tor and controls the regenerative energy produced by the motor.
These fast recovery diodes have faster reverse switching times
than the intrinsic body diode of the MOSFETs used in the PWR-
82331. They also protect the IGBTs used in the PWR-82333
from exceeding their emitter-to-collector breakdown voltage.
Use of a copper case and solder attachment of the output tran-
sistors achieves a low thermal resistance of 0.85° C/W maxi-
mum. Care should be taken to adequately heatsink these motor
drives to maintain a case temperature of 125°C. Junction tem-
peratures should not exceed 150°C. The PWR-82331/33 do not
have internal short-circuit or overcurrent protection. For protec-
tion of the output transistors, these features must be added
externally to the hybrid.

PWR-82331 and PWR-82333
BIAS VOLTAGES
The PWR-82331/33 motor drive hybrids require only a single
power supply for operation. The hybrid generates three inde-
pendent floating supplies, eliminating the need for external bias
voltages for each phase.
In order for the internal power supply to generate these voltages,
the input bias voltage (Vb) must be from +15 to +50 Vdc. In most
avionic systems this can be accomplished by connecting the Vb
pin to the MIL-STD-704D, +28 Volt bus. See FIGURE 3A.
If the system bus voltage is greater than +50 Vdc (and a lower
voltage is not available), then the Vb pin and Vz pin can be tied
together with an external power resistor (Rb) and connected
from these pins to the system power bus. (See FIGURE 3B).
See FIGURES 4 and 5 for bias resistor characteristics.
If additional power dissipation in Rb is a concern, FIGURE 3C
shows a more efficient design, using a low-power resistor (RT)
and an additional transistor. To determine the proper resistor to
use, refer to FIGURE 6.
If there is another voltage available in the system in the +15 to
+50 Vdc range, then this voltage can be directly connected to the
Vb pin of the hybrid.
In any case, a 0.01 mF decoupling capacitor (Cb) must be
connected between Vb (pin 12) and GND.
