提出了一种矩阵式单相电源调压技术,并分析了其工作原理,给出了一种安全的换流策略。仿真结果表明这种变换器输出电压在宽范围内连续可调,而且具有高正弦度的输入电流波形。 Proposed a matrix type single-phase power regulator technology, and analyzed its working principle, gives a safe commutation strategy. Simulation results show that this converter output voltage continuously adjustable in a wide range, but also with high sinusoidal input current waveform.
