Motor Drive Design Features CoolSiC MOSFET

Infineon announces 22 kW reference design for general purpose industrial motor drive

Infineon has introduced a pretested general purpose motor drive reference design which it says reduces the time to market significantly.

The reference design features a nominal power of 22 kW and can be operated directly on a 380 to 480V three-phase grid. The design can be fully re-used for customisation and allows customers to evaluate Infineon's products under real operating conditions. It is suitable for applications like pumps, fans, compressors, and conveyor belts.

The design combines Infineon's latest technologies in one system. The CoolSiC MOSFET IMBF170R1K0M1 with a blocking voltage of 1700 V is the central part of the auxiliary power supply. The design also includes the EasyPIM 3B IGBT7 module FP100R12W3T7_B11 for high current and high-power density, the EiceDRIVER Compact 1ED3131MC12H for optimal EMI performance and low-power losses as well as the XENSIV current sensor TLI4971-A120T5 for measuring high currents with minimal power loss.

The system also contains two microcontrollers - the XMC4800 for control and the XMC4300 for communication, including a pre-installed software package for motor control. This combination allows the evaluation of these products in one design and experience their interaction.

To complete the modular approach, the system is optionally available with a 3D-printed housing, which encloses all electronic components and the cooling system. The housing includes a touchscreen to display current operation conditions, as well as EtherCAT and USB interfaces for external connections.
