摘要
介绍了一种基于电流空间矢量调制策略的矩阵式直流-交流变换器.该变换器的输出电压幅值可达输入相电压的1.5倍、极性任意可调、大小宽范围线性可调,还具有能量双向流动,输入电流零位移、波形接近正弦等特点.基于理论分析,进行实验研究,结果与理论一致,同时表明该变换器具有多象限运行能力.
A novel AC - DC matrix converter is presented in the paper. In the converter, current space vector modulation method and one - step commutation is used. Its output voltage amplitude is 1.5 times that of input phase voltage with a variable polarity. It also features wide output voltage, bi - directional power flow and zero current displacement. Based on the theoretical analysis and experimental researches, the obtained results are consistent. The correctness of and the capability of multi - quadrant operation are proved by the experimental results.
