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 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 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.

and Design Kit

The IRPT2062C

(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 (IRPT2062A)

with a Driver-Plus Board (IRPT2062D). The

Design Kit, IRPT2062E 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
