Shunt based active power factor correction circuit for direct torque controlled PMSM drive

This paper provides the Shunt-Based Active Power Factor Correction for Direct Torque Control of Permanent Magnet Synchronous Motor drive. The intention of the power factor correction is to increase the Power Factor of the circuit concerning to improve the efficacy of controlling the speed of the motor. The preferred circuit has of two parallel rectifiers which provides improve in Power Factor, and reduces the Harmonics in the normal Rectifier Circuit. The simulation of the Shunt based active Power Factor Correction of Direct Torque Controlled PMSM has simulated using MATLAB/SIMLINK.
