摘要
依据热电发电控制器技术指标要求,通过对升压器电感和输出电容的理论计算及实验测试仿真,确定电感和输出电容的参数,并选定输入电容和MOS管的型号。具体参数为:PWM频率为10 kHz,输入电容为100μF,电感为220μH,输出电容是330μF,MOS管选取KD2302。基于上述试验和仿真,设计了Boost型DC-DC变换器,控制算法采用了扰动—观察法。仿真研究表明,该控制算法性能良好,实现了最大功率的跟踪,为后续研究提供了硬件的基础。
Based on technology parameter requirement of a controller for thermoelectric generation,an inductance and an output capacitor can be determined via theoretical calculation and experimental test.Meanwhile,input capacitor and MOS are also chosen.The specified parameters are as follows.PWM frequency is 10 KHz,input capacitor 100μF,inductance 220μH,output capacitor 330μF,MOS KD2302.A built-in DC-DC converter is designed based on the above experiment and simulation,control algorithm is perturbation and observation method.The results of simulation show that the control algorithm has good characteristics,meets the demand of tracking maximum power.This research provides hardware basis for subsequent research.
