Abstract

This paper proposes an active capacitor research method based on difference frequency reactive power theory, which realizes low-frequency power output based on high-frequency input and reduces the volume of passive components at the same time. First, analyze the characteristics of difference frequency reactive power theory, and use the single-phase H-bridge vector modulation strategy to analyze based on the series resonant impedance network. Based on the difference frequency theory, an active capacitance control under a synchronous rotating coordinate system is proposed. Finally, the theory is verified by simulation.
