PROBLEM TO BE SOLVED: To improve reliability and promote size and weight reduction of a device, by a method wherein isolation means which are respectively composed of series circuits of isolation diodes and current protective devices are so provided as to correspond to a plurality of paddle strings, and a generated power is supplied to a load by the isolation means. SOLUTION: Isolation means which are respectively composed of series circuits of isolation diodes 101 -10n and current protective devices 111 -11n are connected to the one side ends of a plurality of paddle strings 11 -1n , respectively. A load 4 is connected to the output side ends of the series circuits of the isolation diodes 101 -10n and the current protection devices 111 -11n through a power controller 3. With this constitution, if the isolation diodes 101 -10n are short- circuited and reverse currents are generated, the current protection devices 111 -11n are turned off to block the flows of the reverse currents. As a result, high reliability can be ensured and, further, a heat exhaustion mechanism can be simplified and size and weight reduction can be promoted. |
