| 摘 要： | 针对三相/单相矩阵式变换器系统,提出一种平均电压脉宽调制方法,通过实时检测三相输入相电压,经过简单计算即可对输出进行正弦调制.采用新型开关器件逆阻式IGBT(RB-IGBT)实现了一台3kW的三相/单相矩阵式变换器样机,并针对RB-IGBT独特的漏电流特性,提出一种基于输入电压大小检测、适用于RB-IGBT的两步换流方法.实验结果表明,该样机可以实现正弦的输出波形.从而证明了本文提出的控制策略和换流方法的有效性和可靠性.

| Abstract: | An average voltage modulation strategy is proposed for three-phase to single-phase matrix converter, which is used to realize sinusoidal output with three-phase input voltages detection and simple calculation. Based on 600V/100A RB-IGBT, a 3kW three-phase to single-phase prototype is built. According to its particular leakage current characteristic, a two-step commutation strategy for RB-IGBT based on input voltage magnitudes detection is proposed. Experiments realize sinusoidal output waveforms, and the results show the validity and reliability of the proposed control strategy and commutation method. |
