摘　　要：针对目前光伏微型逆变器只具备单一并网发电功能、利用率低下以及单相有源滤波器成本较高的不足,结合光伏微型逆变器和单相电流型有源滤波器的运行特点、结构和控制原理,提出了一种针对单块太阳能电池板的新型小功率交错双反激光伏微型逆变器,能够同时实现并网发电及适度无功和谐波补偿功能。详细分析了该系统的工作过程,提出了适用于该系统的相应控制策略,给出有功入网电流指令和无功谐波电流指令的计算方法。PSIM仿真和实验结果验证了系统结构和控制策略的合理性和有效性。Aiming at the shortness of PV（PhotoVohaie） micro-inverter,such as only grid-connection function, lower efficiency and high single-phase active filter cost,a kind of low-power,interleaved dual flyback PV micro-inverter for single solar panel is proposed based on the operating characteristics,structure and control principle of PV micro-inverter and single-phase current-type active filter,which can realize the grid-connection of PV power generation and the moderate compensation of reactive power and harmonic currents. The control strategy of reactive and harmonic compensation system is analyzed,the corresponding control strategy is proposed and the method for calculating the references of grid-connecting active current,reactive current and harmonic current is given. The results of PSIM simulation and experiment show that,the system architecture and control strategy are effective and reasonable.
