无桥星型功率因数校正架构

Two-stage bridgeless power factor correction (PFC) architecture is widely used in high-power ac/dc applications. However, the bridgeless PFC front-end of the two-stage architecture often encounters challenges, such as high switching losses in continuous conduction mode (CCM) or high conduction and magnetic losses in critical conduction mode and other soft-switching modes. These challenges limit th...
