Abstract

This paper presents “A Sepic based AC-DC Convertor using FOPID Controller” is composed of a low-cost, reduced-switch, three-phase ac–dc buck–boost converter is conventional circuit is proposed. The converter can operate with input power factor correction and is suitable for applications where a converter needs to operate over a wide range of input ac voltages and/or produce a wide range of output dc voltages. To solve this problem SEPIC converter with ripple-free input current is proposed. In the proposed converter, the input bridge diode is removed and the conduction loss is reduced. In addition, the input current ripple is significantly reduced by utilizing an additional winding of the input inductor and an auxiliary capacitor. Similar to the conventional PFC SEPIC converter, the input current in a switching period is proportional to the input voltage and near unity powers achieved. The operational principles, steady-state analysis, and design equations of the proposed converter are described in detail.
