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.
DC Power Line Communication (PLC) Reference Design
The DC (24 V, nominal) Power-Line Communication (PLC) reference design is intended as an evaluation module that customers can use to develop end-products for industrial applications leveraging the capability to deliver both power and communications over the same DC power line. The reference design provides a complete design guide for the hardware and firmware design of a master (PLC) node, slave (PLC) node in an extremely small (approximately 1-inch diameter) industrial form factor.
