This work is carried out with the analysis of different single phase rectifiers. We have mention the
different between diode rectifier, thyristor rectifier and PWM rectifier. [1] We are using PWM rectifier in these thesis
work. The research work is carried with the single phase and three phase PWM rectifier. [3] Here we have shown the
uncontrolled and controlled circuit of single phase rectifier. In an uncontrolled rectifier (take switch as diode) is
working as unidirectional means power is not gone back from load to source. And also shown controlled rectifier
(taking switch as IGBT) is working as bidirectional. The SPWM technique is used for providing triggering pulse to the
PWM rectifier as well as inverter.
