REFDR3KIMBGSICMATOBO1: 4kW 3-Ph, 220 ~ 480V Out, 350 ~ 800V In

REF-DR3KIMBGSICMA is a reference design containing two PCBs (named as driver board and power board respectively), including a driver circuit and a three-phase inverter for motor-drive applications. The driver circuit is based on EiceDriver™ IC - 1EDI20I12MH with Miller clamp function. CoolSiC™ MOSFET – IMBG120R045M1H is the main component for the three-phase inverter.

The REF-DR3KIMBGSICMA was developed to support customers during their first steps in designing with EiceDriver™ IC and CoolSiC™ MOSFET for a servo motor with inverter integration. The iMOTION™ MADK EVAL-M1-101T control board can be used to easily evaluate the electrical performance of the system. Also, a heatsink is also provided to represent the motor housing for cooling. Even though the system could work without a cooling fan, a fan and a holder is also included for easy evaluation.
