-Various PWM techniques are used for controlling the different loads such as R, R L, and RLE. In the existing system the control technique like, TSPWM, Single pulse PWM and Multiple Pulse PWM is Used to control the load, which has Acoustic noise and harmonic distortion .The proposed system reveals the reduction of losses by comparing TSPWM, SVPWM and RPWM .The highest possible peak phase fundamental is higher for SVPWM than TSPWM, and the RPWM technique offers significant benefits over deterministic PWM when implementing motor drive system.
