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.
