High-efficiency power conversion architecture for driving a thermoelectric cooler in energy conscious applications

摘要

Systems and methods are disclosed herein relating to an Alternating Current-Direct Current (AC-DC) power conversion system for supplying power to one or more Thermoelectric Coolers (TECs). In some embodiments, a system comprises one or more TECs and an AC-DC power conversion system configured to supply power to the one or more TECs for a high efficiency mode of operation and a high heat pumping mode of operation. The AC-DC power conversion system comprises a first AC-DC power converter configured to convert an AC input to a DC output at a first output power level for the high efficiency mode of operation of the one or more TECs. The AC-DC power conversion system further comprises a second AC-DC power converter configured to convert the AC input to a DC output at a second output power level for the high heat pumping mode of operation of the one or more TECs.
