Abstract
A resonant converter has a primary resonant tank circuit and a secondary resonant tank circuit. An inverter circuit converts an input DC voltage received by the resonant converter at an input voltage node to a pulsating signal that is fed to the primary resonant tank circuit to generate a resonant tank current that flows through a primary winding of a transformer. The resonant tank current induces current in a secondary winding of the transformer. The induced current is rectified by a rectifier and the rectified signal is filtered to generate an output DC voltage at an output voltage node. The secondary resonant tank circuit is disposed between the secondary winding of the transformer and the output voltage node, and a tank node of the secondary resonant tank is connected to the primary resonant tank circuit through the inverter circuit.
