Abstract :
A new reduced-switch, three-phase ac-dc quasi-resonant buck-boost converter is proposed in this paper. The converter can operate with an excellent input power factor correction and is suitable for applications where a converter needs to produce a wide range of output dc voltages and power levels. In the paper, the converter´s operation is explained in detail and its features and its design are discussed. The feasibility of the proposed converter is confirmed with results obtained from an experimental prototype.
