Abstract

A multivoltage power supply which can output a plurality of high voltages in parallel. The voltage values of the respective outputs are feedback to an A/D converter. Each feedback signal is converted to a digital signal and the difference between the digital signal and a corresponding predetermined output voltage is then calculated in the form of a digital value. This digital value is inputted to a corresponding auto-reload timer, whereby a pulse signal having a pulse width corresponding to the digital value is output at a predetermined frequency.
