The power module and motor control system within a page 1 IRPT2056A System Description Power Module The IRPT2056A 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 3phase input bridge rectifiers are rated at 800V. The brake circuit uses 600V IGBT and freewheeling diode. The inverter section employs 600V, short circuit rated, ultrafast IGBT's and ultrafast freewheeling diodes. Current sensing is achieved through 25 mΩ low inductance shunts provided in the positive and negative DC bus rail. The NTC thermistors provide temperature sensing capability. The lead spacing on the power module meets UL840 p...
