This article describes a thermoelectric converter, which is powered by thermoelectric (TE) power modules. This system uses TE devices that directly convert heat energy to electricity to power a converter using direct methanol fuel cell (DMFC) system. The characteristics of the TE module were tested at different temperatures. A boost DC-DC converter was designed and controlled by a power-supply controller chip. Efficiency of about 80% can be achieved and because the thermoelectric converter system has not moving parts and has a small volume, the system can be carried about easily and conveniently to supply portable electric equipment and this is very important for some mobile equipment.
