Abstract

AC/AC matrix converters have recently been applied for industrial, military and aerospace prototype systems. However, their dedicated input filters may lead to instability in operation. In this paper, simulations are presented of a model that accounts explicitly for the switching, and these simulations are compared with an averaged model. It is shown that this averaged model may significantly underestimate the instability threshold compared with the more detailed, switching model, which is instead recommended for determining the stability margin.
