高动态给载波的跟踪带来了很大的困难,本文研究采用锁频环( FLL) 和锁相环( PLL) 相结合的方法来实现 载波跟踪-High dynamic to the carrier' s tracking has led to great difficulties, this paper uses frequency-locked loop (FLL) and phase-locked loop (PLL) methods to achieve a combination of carrie

单相并网逆变器并网电流中含有大量谐波，传统的PI 控制器难以满足波形跟踪需要，此处采用比例+复的复合控制算法用于逆变器电流环控制器设计(The single-phase grid-connected inverter has a large amount of harmonics in the grid-connected current. The traditional PI controller can not meet the needs of waveform tracking. Her
