一种低共模噪声的级联无桥Boost PFC

The conventional bridgeless boost power factor correction (PFC) rectifier is a “paralleled” type bridgeless PFC structure. Although it has the advantages of small on-state loss, least number of components, and no bridge-arm pass-through risk, it cannot be directly used in industrial products due to serious common-mode noise problems. In order to solve this issue, the letter proposes a “cascaded” b...
