152 words
A VOLTAGE REGULATOR COMPRISING (A) A POWER SUPPLY CIRCUIT INCLUDING A PAIR OF TERMINALS FOR RECEIVING AN UNREGULATED D.C. VOLTAGE, (B) A SQUARE WAVE OSCILLATOR CONNECTED TO SAID TERMI NALS FOR ENERGIZATION BY SAID UNREGULATED D.C. VOLTAGE, (C) A PAIR OF SILICON CONTROLLED RECTIFIERS CONNECTED IN PARALLEL TO ONE OF SAID TERMINALS, (D) AN OUTPUT CIRCUIT CONNECTED BETWEEN THE OTHER OF SAID PAIR OF TERMINALS AND SAID SILICON CONTROLLED RECTIFIERS, (E) CONTROL MEANS CONNECTED TO THE OUTPUT OF SAID SQUARE WAVE OSCILLATOR FOR GENERATING TRIGGERING PULSES AND APPLYING THE SAME OF THE GATE ELECTRODES OF SAID SILICON CONTROLLED RECTIFIERS, FUG-01 (F) MEANS FOR CONTROLLING THE TIMING OF SAID TRIGGERING PULSES IN RESPONSE TO VARIATIONS OF THE VOLTAGE ACROSS SAID OUTPUT CIRCUIT, (G) AND MEANS FOR IMPRESSING THE OUTPUT OF THE SQUARE WAVE OSCILLATOR ON THE ANODES OF THE SILICON CONTROLLED RECTIFIERS IN PUSHPULL RELATIONSHIP AND IN SERIES WITH THE UNREGULATED D.C. VOLTAGE.
