Single-axis Motor Control Reference Design with Integrated Power Factor Correction
This reference design demonstrates best practices for integrating both single-axis motor control and power factor correction (PFC) into a single microcontroller. This practice is popular when designing variable-frequency compressors, particularly for HVAC systems. This implementation is optimized to perform using a sensorless Field Oriented Control (FOC) algorithm to drive a permanent magnet synchronous motor (PMSM) and two phase interleaved PFC on the TMS320F2805x microcontroller. The FOC algorithm maintains efficiency in a wide range of speeds and considers torque changes with transient phases by processing a dynamic model of the motor.
