<P>PROBLEM TO BE SOLVED: To provide a power supply device for a thermoelectric element that can be reduced in weight, thickness, and length with a simple structure and can supply steady DC power stably and at low cost to a thermoelectric element that requires a small amount of power, and that causes much less noises and electromagnetic waves when a commercial AC power is converted into a steady DC power for supplying the power to the thermoelectric element. <P>SOLUTION: A power supply device for a thermoelectric element comprises a rectifier for rectifying an AC power input from outside and varying in positive and negative directions and for converting the AC power into a DC power having only one direction, and a charger for charging for supplying the rectified DC power as a steady DC power with a certain amount through the rectifier. <P>COPYRIGHT: (C)2012,JPO&INPIT |
