The objective of this paper is to control a single phase power rectifier using Hybrid PWM (Pulse Width Modulation) to get a required output. Nowadays PWM control technique has become an integral part of the most power electronics system. This technique is the most suitable one for controlling the output voltage of a power rectifier. In this paper the performance of the proposed module is analyzed for various Hybrid modulation techniques and the most suitable technique is identified on the basis of Total Harmonic Distortion present in the supply current waveform. Hybrid PWM technique is used to control Gate signal of power switches of single phase power rectifier. By this way, ON and OFF time of circuit MOSFETs can be controlled to obtain the desired DC output voltage. The performance of the power rectifier with the Hybrid PWM technique is promising and attractive for harmonics free power supply applications.
