Abstract:
Abstract Pulse Width Modulation is a powerful technique for controlling analog circuits with a power sent to a load. PWM is a way of digitally encoding analog signal levels. There are a several PWM techniques which are being employed for diverse applications, a few of them being sinusoidal, square wave, trapezoidal, stair-case, delta, delta-sigma, space vector, harmonic injection, third harmonic PWM technique etc. PWM techniques aim at providing better controllable output voltage along with reduction of harmonics. This paper deals with harmonic analysis performed by trapezoidal PWM techniques using FFT tool of simulink in MATLAB. Keywords:- FFT Tools, Pulse with modulation, Total Harmonic Distortion, Trapezoidal
