Infineon introduces evaluation board for CoolSiC MOSFETs

As silicon carbide (SiC) approaches mainstream adoption for applications such as  photovoltaic and uninterruptable power supplies, Infineon Technologies has developed the EVAL-M5-E1B1245N-SiC evaluation board for SiC in motor drives. It was developed to support customers during the initial 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 three-phase AC connector, EMI filter, rectifier and a three-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 ranges from 340 to 480V AC.

There are four new member of the MADK family, optimised for general purpose drives and servo drives with very high frequency. It features the EasyPack 1B in a six-pack configuration with a 1,200V CoolSiC MOSFET and a typical on-state resistance of 45 mOhm. 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.
