The IRPT2062C control system within a motor page 1 IRPT2062A Power Module The IRPT2062A 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 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 requireme...
