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 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-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. and Design Kit The IRPT2056C (Figure 3) provides the complete power conversion function for a 3 hp (2.2 kW) variable voltage, variable frequency AC motor controller. The combines the Power Module (IRPT2056A) with a Driver-Plus Board (IRPT2056D). The Design Kit, IRPT2056E includes the following: • Complete integrated power stage • Specification and operating instructions • Bill of materials • Electrical schematic • Mechanical layout of the Driver-Plus Board • Software transferrable file for easy design integration • Application information and layout considerations Figure 3.
