This paper studies a full-bridge Static Compensator (STATCOM) from the point of capacitor’s energy storing and its application to power factor regulation. By using this concept to reactive power compensation, a single-phase STATCOM can be achieved with a small size dc-capacitor equipped. Additionally, soft switching technique and low frequency control are applied to reduce switching loss. Due to the minimized-used capacitor, a novel modulation technique and energy storing control method are proposed by considering the high-voltage waveform ripple. In this paper, theoretical analysis and simulation and small-scale experiments were completed to confirm the concept, respectively.
