AbstractA Power Converter Includes A Boost Converter, A Dc/Dc Converter And A Coupler Chain. The Boost Converter Receives A Rectified Ac Input And Generates A High Voltage Output. The Boost Converter Includes A Zero-Voltage-Switching Transistor That Is Operable To Adjust The Power Factor Of The Rectified Ac Input To Generate The High Voltage Output. The Dc/Dc Converter Is Coupled To The High Voltage Output Of The Boost Converter And Is Configured To Generate A Regulated Output Voltage. The Dc/Dc Converter Includes A Complementary Pair Of Zero-Voltage-Switching Transistors That Are Operable To Regulate The High Voltage Output Of The Boost Converter To Generate The Regulated Output Voltage.; The Coupler Chain Is Coupled Between A Current-Carrying Terminal Of The Zero-Voltage-Switching Transistor Of The Boost Converter And Current-Carrying Terminals Of The Complementary Pair Of Zero-Voltage-Switching Transistors In The Dc/Dc Converter The Coupler Chain Is Operable To Reduce The Voltage Across The Current-Carrying Terminals Of At Least One Of The Zero-Voltage-Switching-Transistors.
