High-speed ac/dc converter
Abstract
Abstract AN IMPROVED HIGH-SPEED AC TO DC CONVERTER IS DISCLOSED WHICH HAS A RESPONSE TIME SUPERIOR TO THAT OF EXISTING CONVERTERS. THAT IS, THE DC OUTPUT OF THE CONVERTER REACHES ITS STEADY STATE VALUE IN A SHORTER TIME PERIOD THAN IS POSSIBLE WITH EXISTING AC TO DC CONVERTERS. THE IMPROVEMENT IN RESPONSE TIME IS ACHIEVED BY A UNIQUE CIRCUIT ARRANGEMENT INCLUDING A PLURALITY OF OPERATIONAL AMPLIFIERS. BY MEANS OF THE UNIQUE ARRANGEMENT, A COMPARATIVELY LARGE VOLTAGE PROPORTIONAL TO THE INPUT VOLTAGE IS ADDED TO THE DC OUTPUT INITIALLY AND UNTIL THE DC OUTPUT REACHES ITS STEADY STATE VALUE. THE LARGE VOLTAGE ALLOWS A CAPACITOR IN FILTER CIRCUIT TO CHARGE MORE RAPIDLY THEREBY SIGNIFICANTLY DECREASING THE TIME REQUIRED FOR THE DC OUTPUT VOLTAGE TO REACH A STEADY STATE VALUE. FURTHERMORE, THE CONVERTER OF THE PRESENT INVENTION FEATURES INCREASED ACCURACY AND PRECISION.
