Abstract

A power circuit is provided which has a small current peak value from a power source even when a load current repeats periodically, and a burst flow in a burst period and a non-burst flow in a non-burst period alternates. The power circuit includes a power source section, a power controlling section, and an energy storing section having a storage capacitor being connected to an output terminal, a current controlling circuit to control values of detecting a voltage input from a power source section and a control switching device having a field effect transistor switch and a circuit made up of a capacitor in which a flowing period of an output current is controlled by exerting the field effect transistor switch according to a control signal being produced by detecting a change in an input power voltage using a voltage occurring at another terminal of the detecting resistor.
