To address these challenges, this paper proposes a novel rectification circuit based on the VDR topology, specifically designed for LLC resonant converters, offering simplified gate drive circuitry and improved suitability for high-power-density applications. 1. Introduction. The LLC resonant converter is widely recognized as an effective solution for achieving high efficiency in high-frequency operations. This is primarily due to its ability to perform zero-voltage switching (ZVS) on primary switches and zero-current switching (ZCS) on secondary rectifier switches.. The proposed converter consists of an inverter stage, a secondary-side resonant tank and an active voltage-doubler rectifier. An additional input diode is introduced into the regular push-pull inverter so to make the magnetizing inductance free from being always clamped by the input voltage, and. . In this paper, a wide voltage gain LLC resonant converter based on topology reconfiguration is proposed. The primary inverter bridge can be configured as a full bridge or a half bridge with topology morphing control. With an added auxiliary switch, the secondary rectifier can be configured as a. . ter with the benefits of wide output voltage, wide soft switching characteristics for power devices and high circuit efficiency. Since the series resonant circuit is adopted on the primary side, the power switches re turned on under zero voltage switching and power diodes on the secondary side can.
