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.
