摘要： A resonant converter and voltage stabilizing method thereof are provided. The resonant converter includes a converting stage circuit, a diode-rectifying stage circuit, a filter and load stage circuit, a logic circuit, a driving circuit, and an energy-recycling circuit. The method includes steps of recycling an energy from the filter and load stage circuit to the converting stage circuit when the resonant converter is light- or zero-loaded.

摘要： A series resonant circuit device and a voltage stabilizing method thereof are provided. The series resonant circuit device includes a resonant circuit having at least a resonant capacitor and a resonant inductor, an equivalent capacitor electrically coupled to the resonant circuit, a magnetizing inductor electrically connected to the equivalent capacitor in parallel, a transformer having a primary winding electrically connected to the magnetizing inductor in parallel, and a current impulse circuit electrically coupled to the resonant circuit and synchronized with an input voltage of the series resonant circuit device. The voltage stabilizing method is to provide a current impulse to the equivalent capacitor so as to decrease a current difference between the resonant inductor and the magnetizing inductor when the input voltage varies.
