<p>An apparatus, which may be a heater or cooler, includes a thermoelectric device group having at least one thermoelectric device and an electrical subsystem. The electrical subsystem interfaces the thermoelectric device group to an alternating current (AC) line voltage without utilizing a magnetically coupled structure. In some embodiments the electrical subsystem supplies a rectified signal having a voltage approximately equal to the magnitude of the AC line voltage. In some embodiments the AC line voltage is a standard line voltage of about 90 V to about 250 V.</p> |
