Abstract
A highly efficient current controlled thermoelectric cooling system is disclosed. The highly efficient current controlled thermoelectric cooling system includes a first thermal sink, a second thermal sink, a thermoelectric element, and a variable current source. The first thermal sink has a temperature higher than an ambient temperature while the second thermal sink has a temperature lower than the ambient temperature. The first thermal sink is continuously coupled to the thermoelectric element while the second thermal sink is selectively coupled to the thermoelectric element via a mass. A variable current source provides a controlled current pulse to the thermoelectric element such that heat transfer can be effectively achieved between the thermoelectric element and both thermal sinks.
