温差发电控制系统的设计

针对温差发电受到外界因素的影响会出现非正常工作的情况,文章以独立的温差发电系统作为研究对象,研究了现有的温差发电系统中的温差发电控制器的优缺点,分析导致温差发电控制器工作不稳定的原因,并在现有的温差发电控制器的基础上,提出了利用DC-DC变换器结合MPPT中的扰动观测法进行改进,实验表明,该温差发电控制系统可以有效的解决温差发电的不稳定性。

Design of Thermoelectric Power Generation Control System

In view of the fact that the thermoelectric power generation is affected by external factors,abnormal operation will occur.This paper takes the independent thermoelectric power generation system as the research object,studies the advantages and disadvantages of the thermoelectric power generation controller in the existing thermoelectric power generation system,and analyzes the causes of the unstable operation of the temperature difference power generation controller.Based on the existing thermoelectric power generation controller,the improvement of the disturbance observation method in DC-DC converter combined with MPPT is proposed.The experiment shows that the temperature difference power generation control system can effectively solve the instability of the temperature difference power generation.
