Design and analysis of semiconductor refrigeration system powered by PV Cells

In this paper, recalling the key problems in the development of semiconductor refrigeration system powered by Photo-voltaic (PV) cells, we focus on the design of impedance matching circuit by which the system performance can be optimized to work under maximum power point (MPP) condition. A demo system that coordinates the PV cell, semiconductor refrigerator and proposed matching circuit is designed and tested. Experimental results show that the proposed solution can effectively enhance the performance and robustness of the whole refrigeration system, and fits well in the trend of distributed, miniaturized and environmentally friendly.
