Abstract:
1. A power source circuit for supplying power to a load to be driven, in which a load burst period during which a large amount of a load current flows and a small current period during which a small amount of the load current flows alternately occur, comprising: a power supplying section to generate an electromotive force; a plurality of power storing sections to be charged by said electromotive force fed from said power supplying section and to accumulate power; and a control section to select, during said load burst period, an arbitrary one of said power storing sections that have been already charged and to feed only power that has been accumulated in the selected power storing section to said load, and to feed, during said small current period, power only from said power supplying section to said load, and to charge a power storing section that has not yet been charged, even during said load burst period and even during said small current period.
