摘要
以SPWM多重化为控制技术 ,对电压型并联逆变器的输出特性进行了谐波分析。通过对并联逆变器系统的环流和负载电流的分析 ,给出了一种死区效应补偿的新方法。实验结果表明 ,利用该方法能有效改善并联逆变器系统的输出特性。
Based on multiple-SPWM technique,harmonic of output characteristic for voltage inverters in parallel connection is analyzed.By comparison and analysis about circulating current and load current,a new approach for compensation of dead-time effects is presented.The experimental results show that according to the above approach can improve effectively output characteristic of parallel inverters.
