Closed loop ferroresonant voltage regulator which simulates core saturation

Abstract

Abstract IN A FERRORESONANT VOLTAGE REGULATOR OF EITHER THE TWO CORE OR THE ONE CORE TYPE, THE FUNCTION OF THE SATURATING CORE IS REPLACED BY AN INTERGATING CIRCUIT, A SWITCH, AND AND INDUCTOR. THE INTEGRATAING CIRCUIT IS COUPLED TO THE NORMALLY SATURATING WINDING TO DEVELOP AN INTEGRATING CAPACITOR VOLTAGE PROPORTIONAL TO THE VOLT-TIME INTEGRAL OF THE FERROCAPACITOR VOLTAGE. THE SWITCH COUPLES THE INDUCTOR TO THE NORMALLY SATURATING WINDING IN RESPONSE TO THE VOLTAGE ACROSS THE INTEGRATING CAPACITOR TO REVERSE THE CHARGE ON THE FERROCAPACITOR AND PROVIDE FERRORESONANT TYPE REGULATION WITHOUT THE DISADVANTAGES THAT ACCOMPANY CORE SATURATION. A FEEDBACK NETWORK WHICH VARIES THE CHARGING RATE OF THE INTEGRATING CAPACITOR IN RESPONSE TO LOAD VOLTAGE MAY BE ADDED TO PROVIDE GOOD CLOSED LOOP RGULATION SIMPLY, INEXPENSIVELY AND EFFICIENTLY.
