Abstract
When electric power is obtained from a thermoelectric element, a value of electric current is changed, and two combinations of the electric current value and a voltage value (i, V) and (iand V) are obtained. An electric current value iat which the maximum electric power Wmax can be obtained is obtained using an electric current-voltage characteristic estimated based on the obtained two combinations of the electric current value and the voltage value. The electric current is controlled such that the value of the electric current becomes equal to the obtained value iwhen the electric power is obtained from the thermoelectric element. The value iis represented by an equation,=()/().
