SiC reference design for integrated servo motor and drive, powered by 1200V CoolSiC™ MOSFET and EiceDRIVER™
The REF-DR3KIMBGSICMA reference design which consists of two PCBs (named as driver board and one power board respectively), including a driver circuit and a 3-phase inverter for motor-drive applications. The driver circuit is based on EiceDRIVER™ - 1EDI20I12MH with miller clamp function. The board is designed to evaluate the CoolSiC™ MOSFET – IMBG120R045M1H solution in integrated servo drive applications. It is the main component for the 3-phase inverter. The iMOTION™ MADK EVAL-M1-101T control board can be used to easily evaluate the electrical performance of the system.
