PURPOSE:To detect precisely the voltage and current of a solar battery by adding a compensating means for compensating a detecting time deviation due to the reactance or the like of a detector itself. CONSTITUTION:An electric power generator using solar light detects the voltage and current of the solar battery by a voltage detector 7 and a current detector 8 and controls an electric power converter so that electric power to be taken out from the solar battery is maximized. At the detection of the voltage and current, an amplifier circuit consisting of an operational amplifier 13, an input resistor 14 and a feedback resistor 15 is connected to the output circuit of the voltage detector 7 and a serial circuit consisting of a resistor 16 and a capacitor 17 is connected between the input terminal of the amplifier 13 and the output terminal of the current detector 8. Even if a reactor exists between the solar battery and the detectors 7, 8, the detecting deviation of the reactor can be compensated by the amplifier circuit and a real solar battery voltage can be detected. |
