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.

摘要： A measuring apparatus for measuring power loss of magnetic device is disclosed. The measuring apparatus includes a power converter, a voltage measuring device and a current measuring device. The power converter is connected to the DC power supply and the magnetic device for converting the DC voltage supplied by the DC power supply into a rectangular wave alternating between positive and negative for use by the magnetic device. The voltage measuring device is connected in parallel with the DC power supply for measuring the input voltage of the power converter. The current measuring device is connected in series between the DC power supply and the power converter for measuring the input current of the power converter. The power loss of the magnetic device is substantially equal to the product of the input voltage and input current of the power converter.
