Abstract

A resonance conversion device including an LLC synchronous resonance converter, a synchronous rectification controller, and a dead time adjustment circuit is provided. The LLC synchronous resonance converter includes a resonance tank and multiple synchronous rectification switches. The synchronous rectification controller controls the synchronous rectification switches, which are turned on with a delay based on a dead time length. The dead time adjustment circuit inductively couples electric energy at an output of the LLC synchronous resonance converter to the resonance tank, and provides a dead time control signal according to a resonance voltage variation of the resonance tank so that the synchronous rectification controller adjusts the dead time length according to the dead time control signal.
