1. A power supply comprising:
- a battery;
a power supply circuit connected with the battery for supplying power to a load with CPU, wherein the power supply circuit consists of a plurality of power supply circuits which are able to connect in parallel with one another;
an operation mode detecting means for detecting an operation mode of the load; and
a power supply circuit selecting means for switching any one of or multiple combinations of the plurality of power supply circuits for supplying power to the load, depending on the operation mode detected by the operation mode detecting means, said operation mode detecting means consists of the CPU per se.

Abstract
A power supply in which power conversion efficiency is enhanced in all operation modes by supplying power to a load (60) from any one or both of first power supply circuit (20) and second power supply circuit (40), detecting the operation mode of the load (60) through an operation mode detecting means (65), and controlling switches (11,12) depending on the operation mode of the load (60) to select a power supply circuit for supplying power to the load (60).
