<P>PROBLEM TO BE SOLVED: To provide a power supply apparatus for extracting the maximum power from a thermoelectric power generator and stably supplying power to a load for requiring large power. <P>SOLUTION: The power supply apparatus has the thermoelectric power generator 11 for utilizing a thermoelectric element, a capacitor 13 charged by power generated from the thermoelectric power generator 11, and the load 14 supplied with power discharged from the capacitor 13. The thermoelectric power generator 11 and the load 14 are intermittently connected by a switch 12. A resistance of the load 14 is equivalently converted into a high resistance by a duty ratio of a pulse from a pulse generator 16, and controlled so as to be equal to an internal resistance of the thermoelectric power generator 11. <P>COPYRIGHT: (C)2007,JPO&INPIT |
