Comparisons of Harmonic Interactions Due to Integrated Flyback Micro-Inverters
摘要
Abstract
Harmonic interactions among multiple current feedback controlled flyback micro-inverters and multiple quasi-resonant peak current controlled flyback micro-inverters are studied respectively. Small signal analysis is adopted to obtain the Norton equivalent model of the two kinds of flyback micro-inverters. The resonant mechanism and harmonic interaction analysis methods are introduced. Based on the derived Norton equivalent model, harmonic interactions among multiple the inverters are analyzed and compared, and it discloses that the resonant bandwidth of peak current control is more narrow than that of current feedback control, which means that the former has better damping harmonic interactions performance than the later. Finally theoretical analysis, simulations and experiments have been carried out in respectively, and the two sets of 250W prototype are designed for experimental verification.关键词
