This reference design is a 250W motor drive for a major appliances or similar applications, which illustrates a GaN IPM DRV7308 based high efficiency motor inverter without heatsink, also demo a low standby power design with UCC28911. This reference design shows a method to implement sensorless FOC control for a 3-phase PMSM with a FAST™ software encoder or eSMO. With a modular design, this reference design supports both the C2000™ MCU and MSPM0 series microcontroller daughter-board on the same motherboard. The hardware and software available with this reference design are tested and ready-to-use to help accelerate development time to market. The design details and test results are found in this design guide.
