System Description
The IRPT1058A Power Module
The IRPT1058A 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
single-phase input bridge rectifiers are rated at 800V. The
inverter section employs 600V, short circuit rated, ultrafast
IGBTs and ultrafast freewheeling diodes. Current sensing is
achieved through 75 mlow 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
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.
The IRPT1058A
(Figure 3) provides the
complete power conversion function for a 0.75 hp (0.56 kW)
variable voltage, variable frequency AC motor controller. The
combines the Power Module (IRPT1058A)
with a Driver-Plus Board (IRPT1058D).
