Voltage regulator for a generator with filtered feedback means
Abstract
Abstract TO ENABLE USE OF INTEGRATED CIRCUITS, A FIELD CURRENT TRANSISTOR, BEING SWITCHE BETWEEN CONDUCTIVE AND BLOCKED CONDITION, CONTROLS THE TOTAL SUPPLY OF ENERGY TO THE GENERATOR FIELD, A CONTROL TRANSISTOR IS CONNECTED TO THE FIELD CURRENT TRANSISTOR TO CONTROL ITS CONDUCTION, AND A POSITIVE FEEDBACK CIRCUIT INTERCONNECTS THE TWO TRANSISTORS FOR RAPID ON-OFF SWITCHING. THE EXTENT OF CONDUCTION, AS DETERMINED BY THE CONTROL TRANSISTOR, DEPENDS ON DEVIATION OF GENERATOR OUTPUT VOLTAGE FROM A REFERENCE, FOR EXAMPLE A ZENER DIODE. TO PREVENT RESPONSE OF THE CONTROL TRANSISTOR TO HARMONICS, A VOLTAGE DIVIDER WITH TWO TAPS IS CONNECTED ACROSS THE OUTPUT, A CAPACITOR BEING CONNECTED FROM ONE TAP ACROSS THE VOLTAGE DIVIDER TO SPAN ANOTHER TAP, AND THE REFERENCE VOLTAGE BEING TAKEN OFF THE OTHER TAP, SO THAT THE CAPACITOR CAN ACT AS A SMOOTHING, OR FILTERING CAPACITOR, THE RESISTANCE BETWEEN THE TAPS ISOLATING THE CAPACITOR AND THE REFERENCE POINT OF THE VOLTAGE, AND HENCE THE FEEDBACK CIRCUIT, TO PROVIDE FOR RAPID RESPONSE TO OUTPUT VOLTAGE VARIATIONS.
