PW-85225M6 - Half-Bridge Drive with
Regenerative Clamp
DESCRIPTION
The PW-83225M6, PW-84225M6 and PW-85225M6 are half-bridge
drive modules containing isolated switch drivers, an upper and lower
solid-state switch, and an isolated power supply. In addition, the PW-
84225M6 contains isolated current sensing feedback circuitry and the
PW-85225M6 contains a regenerative clamp protection circuit.
The three modules can be used in any combination to create drives
for brush, brushless DC, or AC induction motors. The current sense
output signal and logic inputs are compatible with DSP/ microproces-
sors and/or FPGA/ASIC circuits used to control the motor drives.
These modular drives are capable of operating from either a 鹵135Vdc
or 270Vdc power source that is electrically isolated from the logic
input signals. The modules are fault tolerant from output shorts, loss
of any or all power supplies, and power supply sequencing.
APPLICATIONS
The high reliability and flexibility of these drives make them suitable
for Military and Aerospace applications. Among the many applications
are: actuator systems for primary and secondary flight controls on air-
craft, fan and compressor motor drives for environment conditioning,
pump motors for fuel and hydraulic fluid, antenna and radar position-
ing, and thrust vector position control of missiles, drones, and RPV's.
