This paper presents the modeling of single phase, three phase rectifiers and suitable controller design for the modeled rectifier circuit the primary application of rectifiers is to derive DC power from an AC supply. Virtually all electronic devices require DC, so rectifiers are used inside the power supplies of all electronic equipment. PWM rectifier is now becoming popular due to its low distortion input current, unity power factor operation, bi-directional power flow ability and can offer excellent dynamic response of the dc output voltage. A three-phase PWM rectifier used together with closed-loop dc–dc converters for converting DC power from one voltage to another is much more complicated. In order to perform the above operation rectifier switches should be controlled properly. Hence it is much needed to design a suitable controller for single phase and three phase rectifier. From the small signal transfer function model, the controller scan be designed and the simulated results are presented.
