PURPOSE: A power supply system which is related with a photovoltaic generator is provided to shorten a charging time of an electric car and efficiently use stored energy. CONSTITUTION: A DC/AC converter(211) provides an AC power to a DC link capacitor(212) by converting a DC power which is developed from a photovoltaic generator(100). A bidirectional DC/AC converter(213) is connected to the DC link capacitor and converts a DC power to an AC power. The DC link capacitor is equipped in an output end of a first power converting unit. The DC link capacitor makes the inputted DC power flat and smooth and stores the DC power in a DC link voltage level. A battery(240) stores a surplus power of generated power. The battery is connected to the DC link capacitor and is supplied with a battery power.
