<P>PROBLEM TO BE SOLVED: To provide a power supply apparatus reducing influence of ripples to output control. <P>SOLUTION: The power supply apparatus includes an output means generating a prescribed output signal It and outputting the output signal It to a load, a detecting means detecting the output signal It outputted by the output means, a control means generating a control signal controlling the output means so that the output signal is within a target signal range based on a detection value of the output signal It, and a range switching means extending the target signal range ΔIt0 when the output signal It is within the target signal range ΔIt0 (time t1, t3 and t5). When the output signal It is out of the extended target signal range ΔIt1 (time t2 and t4), the range switching means narrows the extended target signal range ΔIt1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
