More Information
Summary:A solar simulator includes a flash lamp 103 for radiating light to a solar battery module, a power supply 101 for supplying a current to the flash lamp, switch units 105a to 105c connected in parallel for causing a current to be supplied to the flash lamp when turned on and causing a current to the flash lamp to be shut off when turned off, ballast resistors 106a to 106c interposed between the switch units and the power supply, and a control unit 102 for performing an on/off control of the switch units and sequentially switching a switch unit to be turned on at every predetermined time, prevents thermal destruction of the semiconductors included in the switch units due to a temperature increase. Then, a constant current can be caused to continuously flow through the flash lamp 103 and can be caused to emit light for a long time.
