温差发电技术是一种无污染，无噪声，应用范围广的新型能量收集技术。用特殊材料制成温差发电片。温差发电片冷热端温度不同，就会产生电压，从而使热能转换为电能。利用LTC3108直流升压电路，将温差发电片转换来的低电压升高，就可以供低功耗设备工作。由于温差的变化或者设备间歇工作等原因，转换所得的电量可能会过剩或者不足。为解决上述问题，系统采用超级电容作为储能元件。在电量多余的情况下，将电量储存在超级电容里；在电量不足的情况下，将超级电容所存电量释放出来，供设备使用。%Thermal power generation technology is a kind of new energy harvesting technology with no pol ution, no noise, and wide application. Thermoelectric conversion module is made of special materials. When the temperature of both sides of the thermoelectric conversion module is different, it would form voltage. Thus, thermal energy changes into electrical energy. LTC3108 DC booster cir-cuit is used to boost the low voltage transformed by thermoelectric conversion module. And the boosted voltage can be supplied for low power consumption devices. Because the temperature difference between the two sides of thermoelectric conversion module is changed or the device operation is intermittent, the electrical energy might be surplus or lack. In order to solve this problem, this pa-per uses the super capacitors as energy storage elements. When the electricity is surplus, the rest of the electricity is stored into the super capacitors. And, when the electricity is lack, the stored energy is released to equipments.
