Abstract

Pulse width Modulation technique is implemented for Single Phase AC Voltage Controller or Ac voltage regulator.AC Voltage controller is made switched on and off several times in cycle by using PWM control method. Simulation Model is presented in the Paper and there is Comparison placed in the Paper between the Phase angle Control method and PWM control method. This Paper deals with the harmonic reduction in output voltage. FFT analysis for both Phase angle control and PWM Control is presented. In the PWM technique, the switch of ACVC is turned ON and OFF several times in each half cycle. The width of pulses can be varied for controlling the output voltage. The harmonics is reduced by using the PWM technique. If the harmonics in the input current is high then it can distort the supply voltage. The higher order harmonics in the input current can be filtered with the help of the filters but the lower harmonics cannot be filtered out. So the PWM technique becomes so important to implement for switching the ACVC.

Key Words

Harmonic, Lower order harmonics, THD, PWM control, Phase Angle Control
