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. . Abstract—The resonant current control has been extensively employed to reduce the current harmonic distortion in a wide range of grid-connected distributed generation applications, in-cluding photovoltaic (PV) inverters, wind and water turbines, and fuel-cell inverters. Indeed, the harmonics.

In one simple inverter circuit, DC power is connected to a through the center tap of the primary winding. A switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary and then the other. The alternation of the direction of current in the primary winding of the transformer produces
