CoolSiC MOSFET evaluation board

With silicon carbide (SiC) en route to become mainstream for applications like photovoltaic and uninterruptable power supplies, Infineon Technologies is now targeting the next group of applications for this wide bandgap technology.

A new evaluation board EVAL-M5-E1B1245N-SiC has been developed to help pave the way for SiC in motor drives and will help to strengthen Infineon’s market position for industrial SiC. It was developed to support customers during their first steps in designing industrial drives applications with a maximum of 7.5kW motor output.

The evaluation board comprises an EasyPACK 1B with 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 has been optimised for general purpose drives as well as for servo drives with very high frequency. It features the EasyPACK 1B in Sixpack configuration with a 1200 V CoolSiC MOSFET and 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, which makes it RoHS compliant.
