间接矩阵变换器优化SVPWM及其简化的同步控制
|
摘要
针对间接式矩阵变换器中存在的直流母线电压波动问题,提出一种基于输入电压的空间矢量优化调制策略,用于逆变级优化。为克服传统方法在实现整流级无零矢量调制与逆变级调制策略同步控制的过程中存在的计算量大、调制波形不对称的缺陷,提出一种简化的同步控制算法,该控制算法不需要复杂浮点运算、易于实现。实验结果表明,优化调制策略和简化同步控制算法的应用可改善间接式矩阵变换器的输入输出波形质量。
To solve the problem of high fluctuation of DC-link in indirect matrix converter, an optimized space vector modulation strategy based on input voltage is proposed. Moreover, in the synchronous control of zero vector modulation on rectifier stage and modulation strategy on inverter stage, due to the large amount of computation and the asymmetric modulation waveform of the traditional method, a simplified control algorithm is proposed. This algorithm does not need complex floating-point operation and is easy to be implemented. The experimental results show that the optimized modulation strategy and the simplified synchronization control algorithm can improve the quality of the input and output waveforms of the indirect matrix converter.
