Abstract
An electrical power supply for an electrolytic gas generator includes an input network provided with a first rectifying-flattening circuit for generating a DC voltage from an AC power source voltage input thereto and an output network provided with a switching circuit for generating a pulse voltage having a predetermined frequency from the DC voltage supplied from the input network and a second rectifying-flattening circuit for transforming the pulse voltage into the DC voltage and for supplying this DC voltage to an electrode of the electrolytic cell. The power supply further includes a voltage-adjusting circuit for generating an error signal corresponding to the difference between a feedback signal for any one of a signal corresponding to the output voltage from the output network and a signal corresponding to a detected pressure of the gas generated within the electrolytic cell and a standard signal corresponding to a design pressure of the gas generated so as to maintain the output value of the output network or the pressure of the gas generated at a predetermined design value and further includes a frequency-fixed pulse-width modulator for generating a pulse-signal having a predetermined frequency modulated to a pulse-width corresponding to the error signal and a driver circuit for generating a drive pulse for controlling the switching of the switching circuit in the output network in accordance with the modulated pulse signal from the modulator.
