General theory of switching power converters

摘要

A unified general theory of the operation and performace of switching power converters is presented. It differs from prior approaches in that it addresses converters according to func?? tion rather than topology, and in the way conver?? ter analyses are approached. Relationships be?? tween converters are clarified, the inherent un?? desirable aspects of switching converters are seg?? regated from those specific to particular cases and the act of commutation is shown to be an in?? dependent function of internal converter operation with little influence on external terminal per?? formance. The theory has been well tested in the classroom and used to provide the basis for analy?? ses in a practical working development laboratory. It has withstood both tests; students grasp it readily and from it develop a good understanding of Power Electronics, while in the working environ?? ment it has proved beneficial in facilitating studies and comparisons of converters for many applications, and in aiding design efforts.
