摘要
分析了矩阵式变换器(Matrix Converter,简称MC)的空间矢量调制和双向开关半软换流策略,提出了采用数字信号处理器(DSP)作为控制核心,应用复杂可编程逻辑器件(CPLD)实现半软换流策略的矩阵式变换器全数字控制方案,实验结果表明了这一方法的可行性和可靠性。
The double Space Vector Pulse Width Modulation (SVPWM) scheme and semi-soft commutation algorithm of the matrix converter are dedueed.A digital control strategy based on digital signal processor (DSP) for matrix converter,in which semi-soft current commutation algorithm of the hi-direction switches was implemented by the complex prograrmnable logic device (CPLD),is presented.The experimental results demonstrate the feasibility and reliability of this scheme.
