6.7 IPM Inverter Example
The IPMs integrated intelligence
greatly simplifies inverter design.
The built in protection circuits allow
maximum utilization of power de-
vice capability without compromis-
ing reliability. Figure 6.46 shows a
complete inverter constructed us-
ing dual type IPMs. Input common
mode noise filtering and MOV
surge suppression helps to protect
the input rectifier and IPMs from
line transients. The main power
bus is constructed using laminated
plates in order to minimize parasitic
inductance. Low inductance bus
designs are covered in more detail
in Sections 3.2 and 3.3. An ex-
ample of the mechanical layout of
the inverter is shown in Figure
6.47. The IPMs must be mounted
on a heatsink with suitable cooling
capabilities. Thermal design and
power loss estimation is covered in
Section 3.4. Mitsubishi offers a
complete line-up of diode modules
that are ideal for use as the input
bridge in inverter applications.
