Pow er Module
The IRPT3054A 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 1600V. The brake
circuit uses 1200V IGBT and freewheeling diode. The inverter
section employs 1200V, short circuit rated, ultrafast IGBTs and
ultrafast freewheeling diodes. Current sensing is achieved
through 25 m
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 a mounted to a heat sink with two
screw mount positions, in order to ensure good thermal contact
between the module substrate and the heat sink.
