2008 Microchip Technology 1AN1208INTRODUCTION In recent years, the motor control industry has beenfocusing on designing Power efficient motor controldrives for a wide variety of applications. The consumerdemand for improved Power quality standards is drivingthis trend. The Power quality can be enhanced byimplementing Power Factor Correction (PFC), andefficient control of a motor can be realized usingSensorless Field Oriented Control (FOC) appliance industry often requires low-costimplementation of these algorithms.
