摘 要传感器以及各类微功耗仪表已在各个领域的广泛运用,人们对其使用寿命的要求也不断提高。但是大量应用在无人区域的传感器或者设备的使用寿命都在电源问题上被限制了。对这些设备进行电源的更换是很困难的,而通过使用能量转化的方式将周围环境的各种形式的能量转化为电能供设备使用,相当于增加了电源的容量,延长设备的使用寿命。本课题从光电转化与热电转化中选择热电转化方式,利用半导体的热电效应产生电能。通过升压电路对转化的电能进行升压处理,使其能够满足设备的工作要求。同时选择超级电容代替充电电池来存储所转化电能。通过对半导体发电片以及超级电容的性能测试与分析,来确定通过能量转化方式在这些仪表中代替传统方式的可能性。60927

Abstract
Sensors and a variety of micropower instrumentation has been widely used in various fields, they are also required to improve the service life. But the life of a large number of sensors or equipment applied in the area of unmanned are limited in the power supply problem. The power of these devices is difficult to replace, but the energy conversion using the energy exist in surrounding environment turns other forms of energy into electrical energy for the device, representing an increase of the capacity of the power supply, which means extending the service life of the device. This topic select the method of the thermoelectric conversion from the photoelectric conversion and thermoelectric conversion, using semiconductor thermoelectric effect to generate electricity. Through the boost circuit for boosting energy conversion process, so that it can meet the equipment requirements for the work. While selecting super capacitor instead of the rechargeable battery to store electrical energy conversion. Through the semiconductor chip and the super capacitor power performance testing and analysis to determine the possibilities that using energy conversion in these equipment instead of the traditional way.
Key word semiconductor power chip,supercapacitor
