High voltage power stage delivers dedicated, reliable appliance solution
Integrating industry benchmark three-phase high voltage ICs and rugged
trench IGBTs in a sleek and innovative single in-line package (SIP), IR’s
intelligent power modules (IPMs) deliver a complete power stage solution
for today’s energy-efficient appliance and light industrial equipment driven
by variable speed motors ranging from 400W to 2500W.
The IPMs are an addition to the iMOTION™ family of integrated
design platforms from IR. Together with a few external
components and our IRMCK series of controllers, they form a
complete motor drive system, greatly accelerating the design
path compared to a multi-discrete solution.

Example configuration: Integrated Current Shunt

Built-in over-temperature/over-current protection, along
with short-circuit rated IGBTs, an integrated under-voltage
lockout function, and built-in temperature monitor provide
a high level of protection and fail-safe operation. Other
integrated features, such as bootstrap diodes for the highside
drive function and the single polarity power supply,
simplify overall system design.
Main Configurations
- Open emitter coniguration: flexible architecture to configure current
sensing feedback resistors. Over-temperature is detected internally
and triggers the fault condition.
- Integrated current shunt configuration: a current shunt is included
on the negative bus of the inverter. Over-current is detected internally
and triggers the fault condition.
IR’s iMOTION brings digital controllers, analog stage and power modules
together in one easy to implement, integrated design platform.
