Abstract :
This paper presents a modeling approach to obtain a small-signal model for a single-switch single-phase and three-phase discontinuous boost high-power-factor rectifiers. Such converters present nonlinear characteristics, and an approximation of them is used to derive the models. The most important result obtained is that the small-signal output impedance is not equal to the load impedance. The analysis is validated by experimental results
