Abstract :
This paper introduces a kind of LCC resonant circuit controlled by pulse frequency modulation (PFM). Under optimal control conditions, the design of soft-switch for the power circuit can reduce switching loss. In discontinuous current situations, the working process of the resonant circuit contains dual-pulse and single-pulse output current mode, and the characteristics of two modes is analyzed. In the simulation process, the resonant frequency tracking mode was used to control zero-current turning-on and zero-voltage zero-current turning-off. The applications of the initial current limiting and output voltage rising velocity are realized.
