SiC MOSFET Evaluation Board for Motor Drives up to 7.5kW

Infineon Technologies has announced the evaluation board EVAL-M5-E1B1245N-SiC to help to pave the way for Silicon carbide (SiC) in motor drives. According to the company, Silicon carbide (SiC) is en route to mainstream for applications like photovoltaic and uninterruptable power supplies. The board 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 480VAC.

The new member of the MADK family is optimized for general purpose drives as well as for servo drives with very high frequency. It features the EasyPACK 1B in Sixpack configuration with a 1200V CoolSiC MOSFET and a typical on-state resistance of 45mΩ. 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. The EVAL-M5-E1B1245N-SiC can be ordered now.
