摘要 根据交错反激式光伏并网逆变器拓扑的特点,提出了一种新的控制策略,逆变器在交错反激式的临界连续工作模式、单个反激式的临界连续工作模式和单个反激式的断续工作模式之间交替工作。该控制策略适合于逆变器的各个功率等级,也可以提高逆变器在各个功率等级的效率和并网电流的质量。分析了新控制策略的原理,推导了新控制策略中参考信号和并网电流的关系表达式,并借助Matlab仿真软件证实了该控制策略的可行性。 According to the topology of interleaved flyback for photovohaic grid-connected inverter, a new control strategy was proposed, the inverter worked in the interleaved flyback of mode, the single flyback of BCM and single flyback of discontinous conduction mode alternately . The control strategy could fit all power levels of the inverter and improve the inverter efficiency at all power levels and the quality of grid current. The principle of the new control strategy was analyzed, the relationship between the reference signal and the grid current was derived , and with Matlab simulation software, the feasibility of the control strategy also was proved.
