曼尼托巴整流器—无桥Buck-Boost功率因数校正器

This paper presents a new bridgeless buck-boost power factor corrector with the use of the active virtual ground technique, which is named as the Manitoba Rectifier. The proposed topology can convert the grid ac voltage into a wide range of voltage outputs within a single-stage circuit. It is in a bridgeless structure and simple in design. During the operation, an LC filter is generated at the sys...
