Abstract

A VOLTAGE REGULATOR CIRCUIT FOR FREE VOLTAGE COMPRISING A TRANSFORMER, THE PRIMARY WINDING OF WHICH IS CONNECTED TO A SWITCHING MEANS FOR CONTROLLING POWER SUPPLY TO THE PRIMARY WINDING. A DRIVING MEANS IS ASSOCIATED WITH THE FIRST AUXILIARY WINDING FOR SUPPLING A STARTING CURRENT TO THE SWITCHING MEANS, AND FOR DRIVING THE SWITCHING MEANS AS VOLTAGE AND CURRENT INDUCED AT THE FIRST AUXILIARY WINDING DURING THE "ON" PERIOD OF THE SWITCHING MEANS. A VOLTAGE CONTROL MEANS IS ASSOCIATED WITH THE SECOND AUXILIARY WINDING WITH A DETECTED VOLTAGE PROPORTIONAL TO THE OUTPUT VOLTAGE LEVEL IN CASE THAT THE DETECTED VOLTAGE LEVEL EXCEEDS THE PREDETERMINE VOLTAGE LEVEL. AN OVERCURRENT DETECTING MEANS IS PROVIDED FOR TERMINATING THE SWITCHING OPERATION OF THE SWITCHING MEANS WHEN IMPENDING OVERCURRENT IS DETECTED. (FIG.1)
