Abstract
A power supply circuit includes a series circuit, made up of a current feeding element and a charge storage element, which is coupled in parallel to the output of a power supply source. The power supply circuit also includes a first diode, connected to one terminal of the current feeding element, for feeding a first current from the power supply source to a load, and a second diode, connected to the other terminal of the current feeding element, for feeding a second current from the charge storage element to the load. The charge storage element can be fully charged-up with the voltage coming directly from the power supply source.
