峰值电流控制PFC Boost变换器的时变补偿方法

In this paper, an optimal time-varying compensation method with zero eigenvalue is first put forward for peak current-controlled power factor correction (PFC) boost converter, which can eliminate the fast-scale instability without zero current dead zone and achieve unity power factor. First, a time-varying mathematic model of a peak current-controlled PFC boost converter under continuous conductio...
