摘要：
This paper proposes a dual switch control of a cascaded buck-boost converter for power factor correction application. The proposed control is based on the system model to reduce the current stress and increase the system efficiency. Using the proposed control, the converter operates at a unity power factor, a low total harmonic distortion and low stress on its components. The converter operates in discontinuous capacitor voltage mode (DCVM) which provides inherent high-power factor operation and low switching frequency requirement. The proposed control structure aims to control both stages of the converter independently. The control on the buck stage controls the input current to provide a unity power factor operation, while the boost stage control focuses on reducing the current stress on the converter components.
