Integrated Power Factor Correction (PFC) and Sensorless Field Oriented Control (FOC) System
In recent years, the motor control industry has been focusing on designing power efficient motor control drives for a wide variety of applications. The consumer demand for improved power quality standards is driving this trend. The power quality can be enhanced by implementing Power Factor Correction (PFC), and efficient control of a motor can be realized using Sensorless Field Oriented Control (FOC) techniques. The appliance industry often requires low-cost implementation of these algorithms. This can be achieved by integrating PFC and Sensorless FOC algorithms on a single Digital Signal Controller (DSC).
This application note describes the process of integrating two complex applications: PFC and Sensorless FOC. These applications are implemented on a Permanent Magnet Synchronous Motor (PMSM). In addition, this application note also describes the integration of the algorithms, lists the necessary hardware requirements, and provides the guidelines to optimize the development procedure.
