Abstract
A thermoelectric system which operates on AC input power without requiring external rectification or conditioning is provided. The thermoelectric system includes a thermoelectric device with an integrated rectifier circuit. The thermoelectric device includes a thermoelectric array which may function satisfactorily with 120 volt AC, 240 volt AC or any other desired input power. A control circuit is also provided to allow switching the associated rectifier circuit of the thermoelectric system from full-wave rectification to half-wave rectification. The thermoelectric system may use the control circuit to maintain the temperature of either the hot plate or the cold plate associated with the thermoelectric device at a desired value.
