摘要
Abstract
In this paper, for repressing the resonance of LCL (inductance capacitance inductance) filter, raising output performance of grid-connected photovoltaic inverter, an output filtering means based on notch correction is introduced. The notch correction and leading/delay unit is embedded into the LCL filter, and the design parameter of LCL filter is given. The Simulation and experiment result show this filtering means can availably fall down positive resonance peak of LCL filter, smooth higher harmonic of inverter output current, improve the quality of current waveform, and raise the output efficiency of photovoltaic inverters.关键词
