PURPOSE:To provide the similar solar battery power source which can precisely approximate target voltage-current output characteristics. CONSTITUTION:This similar solar battery power source is equipped with a series regulator 1, an output current detection part 2 which outputs an analog current detection signal S2 corresponding to a load resistance, an output voltage detection part 3 which outputs an analog voltage detection signal S3 of a voltage applied to the load resistance, a substitution part 4 which extracts a current value corresponding to the voltage value of the analog voltage detection signal S3 from output characteristic data of a solar battery and outputs a target current signal IS, and a control part 5 which detects the difference between the current value that the target current signal IS indicates and the actual current value that the analog current detection signal S2 indicates, performs PID control logical operation on the basis of the difference, and outputs a control signal S4 for outputting an analog voltage signal S1 corresponding to the target current signal IS to the series regulator 1. |
