DEVICE FOR GENERATING SIMULATED SOLAR LIGHT FOR SOLAR BATTERY CHARACTERISTIC MEASUREMENT AND METHOD OF GENERATING SIMULATED SOLAR LIGHT

摘要

Disclosed is a device for generating simulated solar light, wherein a switching system is adopted that makes it possible to provide a larger amount of power, that makes it possible to measure the I-V characteristic of a solar battery accurately and with high efficiency, and that makes it possible to increase the time for which arc discharge of a lamp is maintained. Power is supplied to a double-layer accumulator and power control circuit (20) from a charging power source (12) connected with a mains power source (11), and charging is performed by charging control by a control circuit (70). Then, when charging of the double-layer accumulator and power control circuit (20) is completed, a flash lamp (50) is switched on by charging a smoothing capacitor (38) with a prescribed voltage, using the control circuit (70) to control a switching-type power source voltage boosting circuit (30).
