Abstract | A Family Of Power Converter Is Invented. Each Of These Converter Accomplishes Zero Voltage Switching To Minimize Switching Losses. Also By The Application Of Coupled Inductor, Conduction Losses Can Also Be Minimized. The Basic Embodiment Comprises Of Two Switches Connected Across The Input Source. The Switches Are Driven By Asymmetrical Driving Pulses With Variable Duty Cycle. A Capacitor Is Connected To The Node Joining The Two Switches And An Inductor Is In Turn Connected To It. This Inductor Is Connected To An Output Filter Through A Diode. The Output Filter Comprises Of An Inductor And Capacitor And Diode Combinations. This Output Filter Inductor Has Two Coupled Windings Which Minimize Conduction Losses. The Basic Embodiment Can Be Modified To Provide Converter With Boost Output Or Negative Output. The Embodiment Can Also Be Modified For Isolated Converter With Transformer In Both Half Bridge And Full Bridge Circuit. |
