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鈥檇
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鈥檚; 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.
