Abstract

PURPOSE:To stop working with safety, by interrupting current fed to a load on the secondary side of a transformer, to be set in a non-load state, at the time of stopping the working of a converter, and by setting a main switch in an OFF-state. CONSTITUTION:So far as a resonance type converter is concerned, to both the ends of the primary winding of a transformer 20, two main switches 15-16 confronted with each other are connected, and the converter is driven by respective driving circuits 12-13. On the secondary side of the transformer 20, at the directly rear section of a secondary winding having a center tap, a current interrupting circuit 10 for receiving working-stopping signal generated when excess current or the like is generated, and for interrupting secondary side current is set, and a rectifier circuit 21 and a smoothing circuit 22 are connected. Besides, said working-stopping signal is fed also to the driving circuits 12-13 for turning both the main switches 15-16 OFF via a delay circuit 11. Then, the current interrupting circuit 10 is worked, and current fed to a load 14 is interrupted. After delay for a specified period, the main switches 15-16 are set in an OFF-state.
