利用任意两相电压合成交流电压：用于直接交流-交流功率变换的频率、相位和幅值调制

Usually, the dc-link is employed as the intermediate stage of ac–ac power conversion for high controllability, good output quality, and stability, while the large-volume dc capacitors will lead to high equipment failure rate and maintenance cost. This article proposes an arbitrary two-phase input voltages based ac voltage synthesis method for direct ac–ac power conversion, which can realize the th...
