CURRENT CONTROL APPARATUS FOR SOLAR CELL INSPECTION

摘要

A current source circuit (51) is provided with a constant current apparatus (511), which maintains a current value constant by means of variable resistance, and a voltage source apparatus (512) connected in series to the constant current apparatus (511), and irrespective of whether a solar cell is generating power or not, the current source circuit controls constant a current flowing in the direction equal to the current direction obtained when the solar cell is generating power. The constant current apparatus (511) may be configured from a plurality of elements formed by connecting a current regulation diode (514) and a zener diode (515) in parallel to each other.
