22kW design for an industrial general purpose motor drive

The reference design is a general purpose motor drive which features a nominal power of 22kW and can be operated directly on a 380V to 480V 3-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: It 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 CoolSiC MOSFET IMBF170R1K0M1 with a blocking voltage of 1,700V is the central part of the auxiliary power supply. 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.
