Title:
VOLTAGE REGULATOR
Document Type and Number:
Japanese Patent JPS5858614
Kind Code:
A
Abstract:
PURPOSE:Not to give an unpleasant feeling to an operator when turning on an electric power supply, and also to prevent damage of a driving part, by constituting so that prescribed output voltage having no relation to the previous manipulated variable can be obtained when turning on the electric power supply. CONSTITUTION:A variable resistor 2 has a structure which does not stop mechanically even if its control is rotated clockwise or counterclockwise by one rotation or more. Whenever the control is rotated by one rotation, saw tooth voltage Vi is outputted, is supplied to a differentiating circuit 4, and from its output, a signal of a value of DELTAVi/DELTAtheta is supplied to a comparing circuit 6. From the comparing circuit 6, a value which is smaller than a prescribed value, for instance, A, in the output of the differentiating circuit 4 is supplied to an integration circuit 8. Only a value which is smaller than the set value A, in the differentiated value is supplied to the integration circuit 8. In the integration circuit 8, output voltage from the comparing circuit 6 is integrated. From an output of the integration circuit 8, voltage of waveform is outputted, is supplied to an adding circuit 10, an initial value Vs and output voltage Vo of the integration circuit 8 are added, and its result is outputted from its output terminal.
