IRPT1053A
The IRPT1053A Power Module
The IRPT1053A Power Module, shown in figure 1, is a chip
and wire epoxy encapsulated module. It houses input rectifiers
output inverter, current sense shunts and NTC thermistor. The 3-
phase input bridge rectifiers are rated at 800V. The inverter
section employs 600V, short circuit rated, ultrafast IGBTs and
ultrafast freewheeling diodes. Current sensing is achieved
through 45mΩ low inductance shunts provided in the positive
and negative DC bus rail. The NTC thermistor provides tempera-
ture 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 effi-
ciency. The Driver-Plus 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.
