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.
