摘要

提出了一种带整流性负载并网逆变器的控制方法。该并网逆变器可以工作于独立和并网 2种工作模式。分析了并网逆变器带整流性负载对电网电流的影响。通过引入整流性负载电流补偿的方法，消除了整流性负载和滤波电容对电网电流的影响，提高了电网电流的波形质量。该方法控制简单，易于实现。仿真和实验结果表明，在带整流性负载情况下，采用该控制方法可以使并网电流具有很好的正弦度，独立运行时输出电压外特性好。

Abstract

A control strategy for grid-interactive inverters with rectifier loads is proposed. The utility-connected inverters can operate at both stand-alone and grid-connected modes. The impact of the rectifier loads on the grid current is analyzed. The influence of the rectifier load and filter capacitor on the grid current can be eliminated by adding the rectifier load current into the current loop， and the waveform quality of the grid current can be improved. The control method is simple and easy to be implemented. Simulation and experimental results illustrate the improvement of the waveform quality of the grid current and the external characteristics of the inverter at stand-alone mode.
