Abstract
A power supply apparatus includes a power converting unit for switching DC power on the basis of a pulse signal having a predetermined ON-pulse time and a predetermined pulse period, as pulse elements, thereafter smoothing the switched power, and outputting a predetermined power voltage, a control unit for calculating a new pulse-element on the basis of an output of the power converting unit, and a pulse generating unit for generating a pulse signal on the basis of the new pulse-element instructed from the control unit. The pulse generating unit generates the pulse signal of the new pulse-element from the instructed timing without waiting for a next pulse-period, even if the timing for instructing the new pulse-element from the control unit is any timing during the pulse period, irrespective of the ON-pulse time and an OFF-pulse time.
