IRPT1065A
The IRPT1065A Power Module
The IRPT1065A power module, shown in figure 1, is a chip
and wire epoxy encapsulated module. It houses input rectifiers,
brake IGBT and freewheeling diode, output inverter, current
sense shunts and NTC thermistor. The single-phase input bridge
rectifiers are rated at 800V. The inverter section uses 600V,
short circuit rated, ultrafast IGBTs and ultrafast freewheeling
diodes. Current sensing is achieved through 75 mΩ low
inductance shunts provided in the positive and negative DC bus
rail. The NTC thermistor provides temperature sensing
capability. The lead spacing on the power module meets UL840
pollution level 3 requirements.
The power circuit and layout within the module are carefully
designed to minimize inductance in the power path, to reduce
noise during inverter operation and to improve the inverter
efficiency. The driver board required to run the inverter can be
soldered to the power module pins, thus minimizing assembly
and alignment. The power module is designed to be mounted to
a heat sink with two screw mount positions, in order to insure
good thermal contact between the module substrate and the heat
sink.
