Infineon Launches Evaluation Board to Support Motor Design
SiC reduces servo drive power loss by 80%.


Infineon Technologies announced on the 9th that it is providing the 'CoolSiC MOSFET MADK (Modular application design kit) board' that supports fast motor design.

In servo drive applications, silicon carbide (SiC) reduces semiconductor power loss by up to 80%. It eliminates cooling fans, eliminating the need for drive maintenance. Furthermore, it allows for motor and drive integration, reducing cable complexity and freeing up inverter cabinet space.

The MADK EVAL-M5-IMZ120R-SIC evaluation board for motors up to 7.5 kW is a three-phase inverter board for servo drive applications. Infineon provides a download package on its website, including schematics (PDF), components (Excel), layout (Gerber) and design package (Altium).

The evaluation board is designed to support customers designing servo drive applications using CoolSiC 1200V MOSFETs (IMW120R045M1) and EiceDRIVER 1200V isolated gate drivers (1EDI20H12AH). The IMW120R045M1 has a blocking voltage of 1200 V at a rated on-state resistance of 45 mΩ, and the board supports all CoolSiC MOSFETs in 3-pin and 4-pin TO247 packages.

The EVAL-M5-IMZ120R-SIC evaluation board includes a three-phase rectifier EMI filter, current sensor, protection features, thermal management, and a heatsink. All analog and control signals are easily accessible via test pads, and the signals are isolated from the power supply for precise measurements.

It provides a 32-pin interface connector for all control signals, and can be connected to the control board XMC DriveCard 4400 (KIT_XMC4400_DC_V1) with an M5 connector. Combining this evaluation board and control board allows you to design a motor in a short time and with little effort.

The evaluation board is currently available.
