ABSTRACT:
The output from a reference voltage source is provided to a DC amplifier and its output is applied as a reference voltage to an output terminal. The output thus derived at the output terminal and the output from the reference voltage source are changed over by a switch to be alternately supplied to a smoothing circuit, the smoothed output from which is fed back to the DC amplifier. The switch is changed over periodically by a control signal from a control circuit, and by controlling the change-over ratio of the switch, a reference voltage of a desired value is provided at the output terminal. Thereafter, when the output voltage at the output terminal deviates from the reference value, the deviation is corrected by the feedback action.
