摘　　要：将基于叠加原理的过调制处理策略应用于五电平逆变器的过调制区域,详细分析了过调制区域的处理方案,使得处于过调制区域的参考矢量得到有效调整,然后在不同调制度下进行实验,实现了由线性调制区域到六拍阶梯波的平稳转换,实验结果验证了过调制处理方法的正确性和有效性。The over-modulation strategy based on the superposition principle is applied in the over-modulation region of five-level inverter.The processing scheme of the over-modulation region is analyzed to make the reference vector in the over-modulation region be effectively adjusted.And then the smooth transition from the linear modulation area to the six-step wave is achieved by the experiments under different modulation degrees.The correctness and effectiveness of the over-modulation strategy are verified by the experimental results.
