摘要
在非对称输入电压情况下 ,对基于双空间矢量调制的矩阵变换器的输出电压波形进行了分析 ,提出了利用时变调制比改善输出电压波形的方法。在牺牲一定增益和增加少量计算时间的前提下 。
The output voltage waveforms of matrix converter which is based on the space vector modulation are analysed under the unbalanced input voltage.A time variant modulation ratio method is proposed.By using this method,we can still obtain sinusoid and balanced output voltages even when input voltages are unbalanced by decreasing a certain of voltage transfer ratio and increasing a little of calculating time.
