In this work, a unity power factor rectifier based on coupled inductors is presented. Use of coupled inductors has obtained galvanic isolation between AC and DC sides. Suitable switching pattern based on PWM, makes possible unity power factor operation for this rectifier. The proposed rectifier has a symmetrical configuration which any halves acts on one half cycles. This configuration uses minimum number of power electronics elements, no conventional diode bridge, two switches (IGBT) and two blocking diodes. The proposed rectifier uses two simple controls and supplies a dc load on low voltage and high current. The simulations have been executed on PSCAD/EMTDC demonstrate its results and practicability.
