EU-funded researchers proposed active thermoelectric cooling solutions to increase the reliability of aircraft electronics and reduce their overall power consumption.
A well-designed thermoelectric cooler drives heat from a cold surface to a hot one, maintaining an electronic device below its safe temperature. Over the past years, pulse-width-modulation (PWM) control of the supplying current has been used to improve the performance of these systems.
