Abstract

PURPOSE:To reduce the power loss on the spike absorbing circuit and to increase the power converting efficiency for the subject converter by a method wherein the elements, on which a threshold value voltage will be generated, are connected in parallel to the primary side of a transformer and in series to a rectifying element in the direction to which its forward current is running. CONSTITUTION:A rectifying element CR, A Zener diode, an avalanche diode and the like are connected in series. The Zener diode, the avalanche diode Z and the like are connected in such a manner that a threshold value voltage will be generated in the direction where a forward current is running. A capacitor C and the parallel circuit of a resistor R are connected in series to the above series circuit. This circuit is connected to the primary coil of the transformer 1 on the flywheel converter.
