Abstract
Resonant converters with wide voltage gain ranges are achieved by controlling at least one of the primary side resonant circuit and the secondary side rectifier circuit. A switch is included in at least one of the primary or secondary sides, and control of the switch according to a selected mode determines an output voltage of the resonant converter. Embodiments accommodate wide input and output voltage ranges, and are suitable for use in AC-DC power adapters for portable devices with different voltage requirements, such as cell phones, tablets, and notebook computers, as well as in DC-DC converter applications including electric vehicle power systems.
