摘　　要：为了实现太阳能资源在未来电动车控制系统中的合理应用,以及太阳能控制系统传输特性的稳定精度,基于降压斩波电路,利用电感电流断续模式设计了一种3 000 W大功率MPPT太阳能控制系统。通过分析BUCK电路的连续模式与断续模式在输入条件持续变化下不同的输出特性,对主电路在不同输入电压条件下的输出电流进行了测试比较,测试结果表明:断续模式的输出电压稳定,其纹波小于5%,系统的输出特性符合相关标准的技术要求,得出电流电感断续模式更加符合设计要求。In order to realize the suitable applications of solar energy in electric vehicle control in the future,and ensure the precision and stability of system transmission characteristics,a 3 000 W high-power MPPT solar power system,based on BUCK chopper circuit,was designed with the principle of discontinuous-mode in this paper.Under the circumstance of constantly changing input,the output characteristics of continuous-mode and discontinuous-mode buck power stage were different from each other.And several tests about output current were carried out when input voltage is different.The results of tests show that according to the test,the stability of output voltage was more stable under discontinuous current mode,and the ripple is less than 5%.The output characteristics of this system meet the technical requirements.As a result,it＇s more appropriate to use discontinuous-mode to realize the demands of design.
