Abstract

PURPOSE:To lower the cost, by realizing the prevention of the destruction of a high frequency voltage rectifying diode, which is realized conventionally only by a reactor having the rectangular B-H characteristic, due to the limitation of the reverse current of the diode by a reactor using a ferrite core. CONSTITUTION:An ordinary ferrite core is used as the core of a reactor 16 because the reactor 16 is excited in DC by a winding n2 to reduce the hysteresis loss considerably. The spike-shaped voltage of a winding n1 due to a winding n2 is absorbed by a resistance 17 and a capacitor 18. A current IF of a diode 15 and an applied voltage VF are shown in figures. The current of the winding n1 is equal to that of the diode 15 approximately. Consequently, the current IF shown in figure is considered to be flowed to the winding n1. However, when the current is flowed to the winding n2 with the polarity shown in figure, the internal magnetic field is changed by components corresponding to this current, and the hysteresis loss is reduced considerably.
