THERMOELECTRIC COOLER DRIVE CONTROL

摘要

A method of heating or cooling a device using a thermoelectric cooler (TEC) (10), the method including monitoring the temperature differential within the TEC (10), and, if the monitored temperature differential within the TEC (10) exceeds a predetermined range, curbing the TEC (10) drive to an extent sufficient to maintain the monitored temperature differential within said TEC (10) within said predetermined range.
