A power source device minimized in size with required number of switching and energy-storing elements for a power conversion reduced is provided by connecting a first energy-storing element through a first switching element in parallel to a power source, connecting a load circuit having a parallel connection of a voltage stabilizer and a load through a second switching element in parallel to the first energy-storing element, connecting an ON/OFF controller to the first and second switching elements for their controlling, and providing a voltage controller including a second energy-storing element and further switching elements for controlling an output voltage to the load circuit through switching operation of the further switching elements.
