<P>PROBLEM TO BE SOLVED: To provide a power supply capable of saving energy by connecting a power generating means with a power saving unit and performing control efficiently without requiring individual inverters thereby utilizing natural energy effectively and supplying saved power stably to a load, and capable of reducing disturbance outputted from a power supply for the load in order to detect single operation simultaneously with detection of single operation of the power generating means at the compensating section of the power saving unit or a voltage stabilizer. <P>SOLUTION: Since a solar power generating means 8 connected in parallel with a power saving unit 2, a system interconnection control means 10 controlling as the system interconnection inverter of the solar power generating means 8 and generating a disturbance signal for detecting single operation of the solar power generating means 8, a means 11 for controlling a full bridge inverter 6 to reduce the disturbance signal, and a charge acceleration detecting means 14 are provided, single operation can be detected at high speed while reducing disturbance of the load. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
