International rectifier offers powertrain family of power conversion subsystems for ac motors. It now includes two solutions for 1.5 and 7.5 hp ratings: irpt2055 and irpt4052, both accepting 460 v ac inputs. The former features a complete powerinverter stage packaged in a chip and wire module; the latter supplies the inverter as a surface mount assembly on an insulated metal substrate. Both include a driver-plus board which contains a driver function with fault protection and shutdown functions. This protects the circuitry from short circuits and ground faults, and over temperature and overvoltage occurrences.
