POWER GENERATION SYSTEM AND POWER GENERATION CIRCUIT
Abstract(summary):
A power generation system (1) is provided with: a heat source (2), the temperature of which fluctuating with the passage of time; an electrically polarized first device (3), the temperature of which fluctuating with the passage of time according to the change in temperature of the heat source (2); a second device (4) for forming a circuit that is configured to extract electric power from the first device (3); a temperature sensor (8) for detecting the temperature of the first device (3); a voltage application device (9) configured to apply a positive or a negative voltage to the first device (3); and a control unit (10) for controlling the voltage application device in accordance with the temperature of the first device (3) as detected by the temperature sensor (8). The control unit (10) controls the voltage application device (9) so that a positive voltage is applied to the first device (3) when the first device (3) is in a temperature-rising state, and a negative voltage is applied to the first device (3) when the first device (3) is in a temperature-falling state.
