New output regulated one-switch boost and boost-buck three phase rectifiers are presented in this paper. Proposed three phase ac-dc converters have power factor correction (PFC) and input current shaping facility in one power stage. Use of minimum number of control switch in each proposed circuit reduces conversion circuit components, drivers and drive isolation circuits, sensors and control circuits...
A single phase new type AC-DC converter based on SEPIC topology has been proposed in this paper which has power factor correction and input current shaping facilities. The proposed rectifier is input switched and utilizes a bidirectional switch at the input. The rectifier gives buck-boost voltage gain without polarity reversal. The design has been made separately to operate the rectifier as a buck...
