  • Publication number: 20230052567
    Abstract: A thermoelectric power generator includes: a thermoelectric power generation module that includes a heat receiver and a heat dissipater and generates electric power by a temperature difference between the heat receiver and the heat dissipater; a cooling device that cools the heat dissipater; and a control device. The generated power of the thermoelectric power generation module is distributed to consumption power used in the cooling device and effective power used in an external load. The control device includes: a monitoring unit that monitors a state of the cooling device and outputs monitoring data; an adjustment unit capable of adjusting the effective power supplied to the external load; and a control command unit that outputs a control command that controls an adjustment unit based on the monitoring data.
