Regulated voltage converter circuit

Claim 1

DIRECT-CURRENT VOLTAGE CONVERTER APPARATUS COMPRISING AN INPUT TO WHICH A DIRECT-CURRENT VOLTAGE MAY BE APPLIED, AN OUTPUT INCLUDING A RECTIFIER-FILTER FOR PRODUCING A LOAD DIRECT-CURRENT VOLTAGE, AND A TRANSISTOR OSCILLATOR CONNECTED BETWEEN SAID INPUT AND SAID OUTPUT, SAID TRANSISTOR OSCILLATOR COMPRISING A POWER TRANSISTOR HAVING EMITTER AND COLLECTOR ELECTRODES CONNECTED ACROSS SAID INPUT AND HAVING A BASE ELECTRODE, A TRANSFORMER HAVING A PRIMARY WINDING CONNECTED IN SERIES WITH SAID POWER TRANSISTOR EMITTER AND COLLECTOR ELECTRODES ACROSS SAID INPUT, SAID TRANSFORMER HAVING A SECONDARY WINDING CONNECTED ACROSS SAID RECTIFIER-FILTER AND A FEEDBACK WINDING CONNECTED ACROSS SAID POWER TRANSISTOR BASE AND EMITTER ELECTRODES AND ORIENTED FOR PROMOTING BASE CURRENT WHEN CURRENT IN SAID PRIMARY WINDING IS INCREASING, A COMPARATOR TRANSISTOR HAVING COLLECTOR, EMITTER AND BASE ELECTRODES, MEANS FOR PRODUCING A STABILIZED REFERENCE VOLTAGE, SAID REFERENCE VOLTAGE MEANS BEING CONNECTED ACROSS SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES AND ORIENTED FOR PROMOTING CONDUCTION BETWEEN SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES, A FIRST CIRCUIT CONNECTED ACROSS SAID OUTPUT AND CONNECTED IN SERIES WITH SAID REFERENCE VOLTAGE MEANS BETWEEN SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES FOR OPPOSING SAID REFERENCE VOLTAGE BY A DECREASING AMOUNT AS SAID LOAD VOLTAGE DECREASES, A FIRST DIODE CONNECTED ACROSS SAID POWER TRANSISTOR EMITTER AND BASE ELECTRODES AND ORIENTED FOR PREFERENTIALLY CONDUCTING CURRENTS WHICH REVERSE BIAS SAID POWER TRANSISTOR EMITTER AND BASE ELECTRODES, A FIRST RESISTANCE CONNECTED IN SERIES WITH SAID FEEDBACK WINDING AND SAID FIRST DIODE FOR LIMITING CURRENT FLOW THROUGH SAID FIRST DIODE, A SECOND DIODE CONNECTED ACROSS SAID FIRST RESISTANCE AND ORIENTED FOR PREFERENTIALLY CONDUCTING BASE CURRENT OF SAID POWER TRANSISTOR, SAID FEEDBACK WINDING HAVING A WINDING RESISTANCE PROPORTIONED FOR SUBSTANTIALLY DAMPING PARASITIC OSCILLATIONS IN SAID FEEDBACK WINDING, AND A SECOND CIRCUIT CONNECTING SAID COMPARATOR TRANSISTOR EMITTER AND COLLECTOR ELECTRODES IN SERIES WITH SAID REFERENCE VOLTAGE MEANS ACROSS SAID POWER TRANSISTOR BASE AND EMITTER ELECTRODES FOR INITIATING CONDUCTION BETWEEN SAID POWER TRANSISTOR BASE AND EMITTER ELECTRODES WHENEVER THE DECREASE OF SAID LOAD VOLTAGE INITIATES CONDUCTION BETWEEN SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES.
