Overview

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.

Features
  • Peak efficiency >99%
  • No heatsink needed for up to 250W inverter stage, 15-kHz switching frequency
  • 80mm by 55mm compact board size
  • Low-standby power design
  • Modular design with either C2000 or MSPM0 controller daughter-board on the same power motherboard
  • Sensor-less field oriented control (FOC) motor control, supports both FAST and eSMO
  • User-friendly graphical user interface (GUI) to control, identify, and monitor the motor
