High-Power SiC Integrated Power Module (IPM) For Motor Applications

620
 

Offers robust thermal performance and electrical isolation while meeting EMI requirements and overload protection

Providing a compact inverter solution with excellent thermal conduction and a wide range of switching speed for three-phase AC motors and permanent magnet motors is the new 1200 V transfer moulded silicon carbide (SiC) integrated power module (IPM), the CIPOS Maxi IPM IM828 series. Applications include industrial motor drives, pumps drives and active filters for heating, ventilation and air conditioning (HVAC).

The CIPOS Maxi IPM integrates a 6-channel 1200 V silicon on insulator (SOI) gate driver and six CoolSiC MOSFETs for increased system reliability, optimised PCB size and reduced system costs. It comes packaged in a small DIP 36x23D housing with a high power density and best-in-class performance. The IM828 series features an isolated dual-in-line moulded housing for excellent thermal performance and electrical isolation while meeting EMI requirements and overload protection of demanding designs.

The rugged 6-channel SOI gate driver of the SiC IPM provides built-in dead time to prevent damages from transients. It also offers under-voltage lockout (UVLO) at all channels and over current shutdown protection functions. With its multi-function pin, this IPM allows high design flexibility for various purposes.

Adding to the protection features, the IPM is equipped with an independent UL-certified temperature thermistor. The low side emitter pins can be accessed for phase current monitoring making the device easy to control.

The CIPOS Maxi IM828 series is now available and can be ordered from Infineon Technologies. It comprises 20 A IM828-XCC for power ratings of up to 4.8 kW.
