This control strategy, which employs simultaneous output-voltage and input-current space vector modulation, can regulate the input/ output sinusoidal waveforms of matrix converter with unity input power factor and ensure the good drive performance of induction motor. 空间矢量调制采用输出线电压和输入电流矢量同步调节的控制策略,能实现矩阵式变换器输入输出波形良好的正弦和功率因数为1,并能确保感应电机良好工作。
In succession, input matching circuit is designed based on simultaneous optimum noise and input matching principle and output matching circuit is designed as well based on conjugate matching principle respectively by using Smith chart and CAD method. 然后利用圆图和CAD软件分别按照最佳噪声和输入匹配原理,设计了输入匹配电路;按照共轭匹配原理设计了输出匹配电路。
