Abstract
This paper presents a new synchronous rectifier method for a LLC resonant converter with voltage-doubler. The pulse width of secondary rectifier cannot be obtained in LLC resonant converter based on the primary side current because primary current include not only the current that is transferred to the secondary side but also the magnetizing current. In the proposed method, the pulse width of synchronous rectifier is obtained from the voltage across the secondary capacitor in the voltage-doubler rectifier.
