Abstract
A power generation control device is provided for controlling a power generator that charges a battery. The device includes a light-emitting diode having a first terminal connected to the battery, an internal power supply activation circuit that activates an internal power supply circuit, a light-emitting diode drive circuit connected to a second terminal of the light-emitting diode, the light-emitting diode drive circuit drives the light-emitting diode in accordance with a power generation state of the power generator, and an impedance conversion circuit that controls in such a manner that an impedance of the internal power supply activation circuit is higher when the light-emitting diode driven by the light-emitting diode circuit is turned off than when the light-emitting diode is turned on.
