PURPOSE:To start a power converter with good response by shortcircuiting the output of a solar light generator by a switch element of a stepup chopper circuit when a solar light power generator system is stopped, thereby collecting an electromotive force by the shortcircuiting current. CONSTITUTION:The DC output of a solar battery 11 is converted through a power converter 13 to an AC, and connected through a switch 15 with an AC power system 14. The converter 13 has a stepup chopper 31 and an inverter 32, which are controlled by a controller 43 together with a current detector 42. Thus, when a solar light power generator system is stopped, a switch element 312 connected between DC terminals 301 and 302 of a solar battery 11 is operated, and shortcircuited through a DC reactor 311. The current in the shortcircuiting circuit is detected by a current detector 41, a level is detected from the signal 411 by the current detector 42 to monitor the electromotive force of the battery 11, thereby starting the converter 13. |
