Claims

1. A VOTAGE REGULATOR FOR AN ALTERNATING CURRENT GENERATOR HAVING AN EXCITATION WINDING AND OUTPUT WINDINGS, COMPRISING A REFERENCE BRIDGE, MEANS INCLUDING A FULL WAVE RECTIFIER FOR CONNECTING THE REFERENCE BRIDGE TO THE OUTPUT OF SAID GENERATOR, SAID MEANS PROVIDING AN INPUT VOLTAGE TO SAID BRIDGE HAVING A D.C. COMPONENT AND A RIPPLE COMPONENT, MEANS FOR SHAPING THE RIPPLE VOLTAGE TO A SAW-TOOTHED APPROXIMATION, SAID BRIDGE BEING PROPORTIONED SO THAT AN INCREASE IN OUTPUT VOLTAGE OF SAID GENERATOR OVER A PREDETERMINED VALVE GIVES A DECREASE IN OUTPUT FROM SAID BRIDGE AND A DECREASE IN OUTPUT VOLTAGE OF SAID GENERATOR UNDER SAID PREDETERMINED VALUE GIVES AN INCREASE IN OUTPUT FROM SAID BRIDGE, THE OUTPUT OF SAID BRIDGE BEING A SAW-TOOTHED APPROXIMATION WITH AN AVERAGE D.C. LEVEL INVERSELY PROPORTIONAL TO SAID GENERATOR OUTPUT VOLTAGE, A THREE STAGE TRANSISTOR AMPLIFIER WITH EACH STAGE DESIGNED TO BE SLIGHTLY OVERDRIVEN, MEANS CONNECTING THE OUTPUT OF SAID BRIDGE TO THE INPUT OF SAID AMPLIFIER.
