| 摘 要： | 换流问题是矩阵变换器工业应用的主要障碍之一.基于双电压合成策略,分析了传统的四步换流策略由于换流时刻存在延迟,降低了换流可靠性,并且会导致输入和输出波形发生畸变.根据四步换流策略的原理,将四步换流缩短为两步换流,大大减少了换流时间.利用Matlab/Simulink软件建立了相应的仿真模型,并利用dSPACE硬件实时仿真平台进行了实验.仿真和实验结果表明,两步换流策略提高了换流可靠性,改善了输入输出波形质量,其输出电流THD值(总谐波畸变率)由4.68%降为2.67%.

| Abstract: | The commutation problem of matrix converter is one of the major reasons that there are few practical applications.The process of traditional four-step commutation strategy is analyzed based on two-line voltage synthesis,which reduce the reliability of commutation and induce the distortion of input and output waveforms because of the delay of commutation moment.Then two-step commutation strategy is presented by reducing the commutation time of four-step commutation strategy.The simulation model of matrix con... |
