摘要
Abstract
A unified large signal and small signal model for DC/DC converters under average current control is presented in the paper. The model can be applied to Buck, Boost and Buck-Boost converters. The proposed model consists of two parts. The first part is an averaged circuit model, and the second part is a model for average current mode control with pulse width modulation (PWM). The model is verified by a Boost converter prototype under average current mode control. The experimental results demonstrate that the model can accurately predict the steady-state, small signal and large signal dynamic behavior of DC/DC converter under average current control.关键词
