【摘要】：分析了Boost變換器的輸出電壓紋波,將谷值V2控制技術應用于Boost變換器。詳細分析了谷值V2控制Boost變換器的工作原理,討論了系統(tǒng)的穩(wěn)定性,研究了斜坡補償對其穩(wěn)定性的影響。搭建了基于PSIM軟件的仿真模型和實驗平臺,仿真及實驗結果表明:工作于連續(xù)導電模式的谷值V2控制Boost變換器穩(wěn)定工作范圍為占空比大于0.5;在占空比小于0.5時會發(fā)生次諧波振蕩,該次諧波振蕩可以通過加入適當的斜坡補償有效地消除。
[Abstract]:The output voltage ripple of the Boost converter is analyzed, and the valley V2 control technology is applied to the Boost converter. The working principle of valley V 2 controlled Boost converter is analyzed in detail. The stability of the system is discussed and the effect of slope compensation on the stability of the converter is studied. The simulation model and experimental platform based on PSIM software are built. The simulation and experimental results show that the stable operating range of Boost converter controlled by valley V2 operating in continuous conduction mode is more than 0.5 duty cycle. The subharmonic oscillation will occur when the duty ratio is less than 0.5, which can be effectively eliminated by adding appropriate slope compensation.
