Infineon Technologies AG’s new evaluation board, the EVAL-M5-E1B1245N-SiC, will help pave the way for silicon carbide (SiC) in motor drives, says the company. SiC is en route to mainstream for applications like photovoltaic (PV) and uninterruptable power supplies (UPS). Targeting the next group of applications for this wide-bandgap technology, Infineon claims to have developed the new evaluation board to support customers during their first steps in designing industrial drive applications with a maximum of 7.5-kW motor output.
The evaluation board features an EasyPACK 1B in Sixpack configuration with a 1200-V CoolSiC MOSFET (FS45MR12W1M1_B11) and a typical on-state resistance of 45 mΩ. It also has a three-phase ac connector, an electromagnetic-interference (EMI) filter, a 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 covers 340 to 480 V ac.
The new member of the MADK family is optimized for general-purpose drives as well as for servo drives with very high frequency, says Infineon. The power stage contains sensing circuits for current and voltage; it's 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 lead-free terminal plating, thus making it RoHS-compliant.
