In order to meet the input and output requirements of an ac-dc converter used for magnet loads, a single-phase two-stage cascade switch-mode rectifier topology for a magnet load power supply is proposed. The first stage is a single switch boost rectifier to shape the input current in phase with the supply voltage. Second stage consists of a dc chopper, which satisfies the steady state and dynamic requirements of such kind of power supply. Judicious use of feedback and feedforward loops enhances the steady state and dynamic performance of the second stage. Novel circuit topology reduces the overall component count, system cost and offers a simple control.Index Terms-Switch-mode power supply, unity power factor operation, and hybrid controller.
