SiC development board shortens time to market for servo drives

Infineon’s CoolSiC MOSFET Modular Application Design Kit (MADK) boards now include the EVAL-M5-IMZ120R-SIC, three-phase inverter board for servo drives.

Details of schematics, parts, layout and the design package are available to download from the Infineon website. The PDf, Excel, Gerber and Altium files can be used with the board as a reference design.

The evaluation board was developed to support customers during their first steps designing applications with the CoolSiC MOSFET 1200V in discrete packages (IMW120R045M1) and EiceDRIVER 1200V isolated gate driver (1EDI20H12AH). It will introduce designers to SiC in servo drive applications, where it can reduce semiconductor power losses by up to 80 per cent. Making use of SiC technology can lead to zero maintenance of drives since fans might not be needed for cooling, says the company. Additionally, it allows the integration of motor and drive with less complex cabling making inverter cabinets redundant.

The assembled discrete has a rated blocking voltage of 1200V at a typical on-state resistance of 45 mOhm and the board supports all CoolSiC MOSFETs in three- and four-pin TO247 packages.

The evaluation board integrates a three-phase rectifier EMI filter, current sensors, and protection features as well as thermal management and heatsink. All relevant analogue and control signals are easily accessible with test pads. To ensure precise measurements the signals are isolated from the power part.

The board is equipped with a 32-pin interface connector for all control signals (an M5 connector) which fits to the controller board XMC DriveCard 4400 (KIT_XMC4400_DC_V1).

The evaluation board EVAL-M5-IMZ120R-SIC can be ordered now.
