A first method is described in which zero voltage switching is achieved by operating the circuit with a variable frequency so that each switch in its on state remains on until the magnetizing current in a main inductor is reversed to a current magnitude sufficient to drive a zero voltage switching transition for a main switch. A second method is implemented with a main coupled inductor wherein a winding current is reversed and energy in a leakage inductance drives a zero voltage switching transition for a main switch. A third method is implemented with auxiliary inductors, auxiliary switches, and auxiliary capacitors which reverse the current in the auxiliary inductor which provides the necessary energy for driving a zero voltage switching transition for a main switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zero voltage switching flying capacitor power converters","description":"Circuit structures and methods are described for achieving zero voltage switching in flying capacitor converters for both isolated and non-isolated applications.
