Pulse Width Modulated AC Voltage Controller Filter Design by Optimization Technique

The AC voltage controller plays a vital role in many of the industries. In this paper the multiple pulse width modulated AC voltage controllers is designed for analyzing the different loads. The performance of AC voltage controller is analyzed with and without filter. The performance parameters are output voltage and total harmonic distortion. The performance analysis is done for pulse width modulated AC voltage controller with resistive load and combination of resistive and inductive load. The design of passive filter components is obtained using particle swarm bacterial foraging optimization technique. The effect of filter requirements is analyzed using the Matlab software.
