| Abstract: | A one-cycle controlled Boost power factor correction(PFC) converter with double frequency was proposed based on that a low frequency unit was added on the base of traditional high frequency Boost PFC converter.The effciency of the converter and performance of the system were improved,which was suitable for high power applications.One-cycle control was adopted as the control mode for this circuit,which simplified the control circuit.Simulation and experiment results showed that the proposed PFC achieved high... |
