ABSTRACT

This chapter introduces a simple and elegant approach to the modeling of the low-frequency behavior of power switches in square-wave power converters, which is known as the minimum separable switching configuration (MISSCO) method. It introduces a simple and effective method for modeling the low-frequency behaviors of switches in square-wave dc-to-dc converters. Simplification of the switching circuit to a minimum configuration before the modeling process has proved to be an efficient way of simplifying the modeling process. The low-frequency behavior models for various converter circuits and electronic transformers have also been developed. The linear circuit elements in the model are, of course, valid for both small-signal and large-signal conditions. It should also be noted that the low-frequency behavior models of power converters are valid only for signal frequencies up to less than half of the switching frequency.
