Abstract:
A power supply circuit includes a thermoelectric conversion element configured to generate electric power when it is differentially heated, an adjustable current circuit configured to draw a current from the thermoelectric conversion element and resultantly output a constant current over a period of time, a voltage conversion circuit configured to output a voltage based on the current output by the adjustable current circuit, and a control circuit configured to control the adjustable current circuit to change a target value of the constant current output by the adjustable current circuit.

Claim (Index 19):
A circuit for controlling the current drawn from a thermoelectric conversion device and supplied to a load, comprising:\n a pair of input terminals and a pair of output terminals, the pair of input terminals connected to the output terminals of the thermoelectric conversion device and the pair of input terminals connected to the input terminals of the load; an inductor connected to one of the pair of input terminals; a first switching element connected in series with the inductor and switchable between a closed position wherein current can flow therethrough and an open position wherein current is blocked from flowing therethrough; a second switching element connected in series with the inductor and switchable between a closed position wherein current can flow therethrough and an open position wherein current is blocked from flowing therethrough; a capacitor connected in parallel with the first and second switching elements and across the output terminals; a current detection circuit connected in series with the first switching element and the other of the input terminals; and a pulse generator connected to the first and second switching elements and a control circuit, the pulse generator configured to generate pulses capable of opening and closing the first and second switching elements, and the duration of the pulses is selectively variable by the operation of the pulse generator; wherein the control circuit is configured to change the duration of the pulse generated by the pulse generator received by the first switching element to open the first switching element based on the value of the current flowing through the first switching element in the closed position as detected by the current detection circuit.
