AbstractAn Ac/Dc Power Converter Includes A Pair Of Input Terminals, A Boost Unit, A Dc/Dc Converter, A Coupler Chain, And A Discharge Chain. The Pair Of Input Terminals Connect To A Pulsating Dc Source. The Boost Unit Is Coupled To The Input Terminals And Generates A Voltage Higher Than The Voltage At The Input Terminals. The Dc/Dc Converter Couples To The Boost Unit And Includes A Set Of Series Switches Coupled To The Primary Side Of A Transformer Through A Series Inductor And Capacitor. The Dc/Dc Converter Further Includes A Secondary Winding Coupled To The Transformer And Coupled To A Rectifier And Filter Configuration. The Coupler Chain Couples The Boost Unit To The Dc/Dc Converter. The Discharge Chain Couples The Coupler Chain To The High Voltage Source Generated By The Boost Unit.; Control Pulses Synchronize The Series Switches So That A Resonant Current Flows In The Coupler Chain And The Discharge Chain Such That The Switches Can Be Turned On And Off While Voltages Across The Switches Are Substantially Zero.
