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.

In this paper we investigate a new modulation technique for the control signals of grid-connected PV inverters. The inverters are connected to the grid via an L-filter. This technique improves the quality of the energy injected into grid by minimising the THD of the currents.. Author to whom correspondence should be addressed. A grid-forming converter (GFM) controls power output by adjusting the phase angle and amplitude of its output voltage, providing voltage and frequency support to the power system and effectively enhancing system stability. However, it has. . Although traditional transformer-based grid-connected PV inverter provides galvanic isolation for leakage current, it suffers from major drawbacks of high cost, lower efficiency, and increased size. Transformer-less grid-connected PV inverter (TLGI) has emerged as a prominent alternative as this. . This paper proposes a control method for reducing the total harmonic distortion (THD) of the grid current of three-phase grid-connected inverter systems when the grid voltage is distorted. The THD of the grid current caused by grid voltage harmonics is derived by considering the phase delay and. .
