Using a pulsed electrical current enables a temporary state in which a Peltier element achieves temperatures below that obtained with a steady current. This is referred to as supercooling. Supercooling is followed by a period of superheating during which Peltier heat transfer is diminished and the surface temperatures increases. Most studies have found that the duration of superheating is longer than the duration of supercooling. As a result, the current pulse generates a net heating instead of enhanced cooling. There are limited studies that have shown the possibility of net cooling during a current pulse. The objective of this paper is to discuss the operating conditions for which net cooling is possible and maximized. The interaction between pulse duration and pulse height using isosceles shaped current pulses on net cooling was investigated using response surfaces generated using electrical-thermal analogies in SPICE. Pulse duration ranged from 0.1 to 10.0 seconds and pulse height ranging from 1.01 to 6.0 times steady current. Response surfaces were used to map a variety of performance factors; including the transient time to achieve a minimum temperature, the pulse cooling enhancement, transient penalty and transient advantage. The optimal combination of pulse duration and pulse height was identified.

New alternatives and inventive renewable energy techniques which encompass both generation and power management solutions are fundamental for meeting remote residential energy supply and demand today, especially if the grid is quasi-inexistent. Solar thermoelectric generators mounted on a dual-axis sun tracker can be a cost-effective alternative to photovoltaics for remote residential household power generation. A complete solar thermoelectric energy harvesting system is presented in this paper for energy delivery to remote residential areas in developing regions. To this end, the entire system was built, modeled, and then validated with the LTspice simulator software via the thermal-to-electrical analogy schemes. Valuable data in conjunction with a novel LTspice circuit were obtained, showing the achievability of analyzing transient heat transfer with the SPICE simulator; however a few of the problems to be solved remain at the practical level. Despite the unusual operation of the thermoelectric modules with the solar radiation, the simulation and measurements were in good agreement, thus validating the new modeling strategy.

Abstract-The objective of this work was to develop a PSPICE-compatible equivalent circuit of a thermoelectric cooler (TEC). Equivalent circuits are convenient tools for power electronics engineers since they help in presenting a problem in electronic circuit terms and can assist in the design of power stages and the control circuitry and algorithms. A methodology is developed for extracting the parameters of the proposed model from manufacturers' data of TECs. The present model is compatible with PSPICE or other electronic circuit simulators. An important feature of the model is its ability to generate small-signal transfer functions that can be used to design feedback networks for temperature-control applications. Several examples of successful utilization of the model are presented. Data of many different manufacturers were examined and the model parameters were extracted. In all cases, the model was found to reproduce accurately the performance of commercial TECs. The accuracy of the model was also verified by experiments.
