Summary: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
