PROBLEM TO BE SOLVED: To solve the problem that a maximum power point tracking control based on a conventional slope climbing method has insufficient control convergence and is unstable, when a power conversion circuit having a maximum power point tracking control function is inserted between a power conversion circuit and a load to obtain impedance matching between a thermoelectric power generation element and the load, in a thermoelectric power generation system. SOLUTION: An internal conductance of the thermoelectric power generation element is measured, an effectual input inductance of the load via the power conversion circuit is measured by measuring input current and voltage of the power conversion circuit in an operation state, and control is performed so that its value may match the internal conductance of the element.
