摘要: 建立连续峰值电流型PFC Boost变换器的时变模型,动态分析快时标不稳定现象的产生,并结合电路试验,分析常规固定斜坡补偿的不足.以斜坡补偿时变模型为基础,以工频输入电流正弦化为目标,提出一种全局优化的动态时变补偿设计理论和方法.基本原理电路试验结果表明全局优化动态补偿既消除了快时标不稳定现象,又获得了单位功率因数,达到了全局补偿优化的目的.

Abstract: A time-varying model of power-factor-correction (PFC) Boost converter with peak continuous current control is built up,and the fast scale unstable phenomenon is analyzed dynamically,the shortage of ramp compensation with constant value is studied with circuit experiments.A global optimization theory and strategy of dynamic ramp compensation is proposed to get sinusoidal input line current.The experimental results show that this global compensation can eliminate fast-scale instability and get unity input power factor with the strongest stabilizing power at the same time,and arrive at global optimal compensation.

Key words: PFC Boost converter, fast-scale unstability, time-varying mode, ramp compensation, global dynamic optimization
