Infineon Technologies has developed an evaluation board to help designers use the latest silicon carbide (SiC) MOSFETs for motor control in systems up to 7.5kW

The wide bandgap technology is en route to mainstream for applications like photovoltaic and uninterruptable power supplies, and Infineon is now targeting the next group of industrial applications.

The EVAL-M5-E1B1245N-SiC evaluation board will help to pave the way for SiC in motor drives. It combines an EasyPACK 1B power module with a 1200V CoolSiC MOSFET (FS45MR12W1M1_B11), a 3-phase AC connector, EMI filter, rectifier and a 3-phase output for connecting the motor. Based on the Modular Application Design Kit (MADK) the board is equipped with the Infineon standard M5 32-pin interface which allows the connection to a control unit such as the XMC DriveCard 4400 or 1300. Its input voltage covers the range of 340 to 480 V AC.

The board is optimized for general purpose drives as well as for servo drives with very high frequency as the 1200 V SiC MOSFET has a typical on-state resistance of 45 mΩ. The power stage contains sensing circuits for current and voltage; it is equipped with all assembly elements for sensorless field oriented control (FOC). The EVAL-M5-E1B1245N-SiC has a low inductive design, integrated NTC temperature sensors and a lead-free terminal plating, making it RoHS compliant.

The EVAL-M5-E1B1245N-SiC can be ordered now.
