摘要
该文阐述了矩阵变换器双电压控制的基本原理。重点分析了在一个开关周期内输入线电流的合成情况。根据双电压合成原理进行仿真,验证了理论分析的正确性。具体分四种输入情况,反映这种调制策略在输出线电压上的优良特性以及输入电流的瞬时值与平均值的变化,并分析该电流的谐波成分。由此指出在输入端设计滤波器的必要性。
The basic control principle of two-voltage synthesis for matrix converters is dealt with in this paper. The general synthesis things of input currents are emphatically analyzed in a switch period. A simulation is carried out to verify the correctness of its theoretical analysis according to two-voltage synthesis principle. The input voltages are divided into four cases so as to embody the excellent properties of output line to line voltage and input instantaneous current and its average based on this modulation strategy. Further, the harmonic elements of this current are analyzed. So it is essential to design filters on the output side of the matrix converter.
