    Two hundred years ago the U.S.A. was born. Seven years ago the PESC came into being. A degree of similarity exists in that both are dynamic in nature, continually being challenged by new frontiers. The principal motivation behind this annual conference is to bring to a central forum current and specialized component and systems technology in the three major disiciplines (electronics, power, and co...

    One would be hard pressed to describe the current status of power electronics analysis and design with a single word, but it may very well be “dynamic.” Analysts have responded to the unique challenges in Dower electronics by developing a somewhat bewildering array of analytical tools and techniques. Yet this same diversity of approach serves diverse purposes in a variety of applications. View full abstract»

    A continuous, low-frequency, small-signal averaged model for the tapped-inductor boost converter with input filter is developed and experimentally verified, from which the dc transfer function and the small-signal line input and duty ratio input describing functions can easily be derived. A new effect due to storage-time modulation in the transistor switch is shown to explain observed excess filte... View full abstract»

    Using state variable representation a nonlinear, discrete-time system is derived that models the converter exactly. This system is linearized about its steady state solution, and converter stability, transient response and audio susceptibility are studied. The steady state solution of the converter is stable if and only if all the roots of the linearized system are absolutely less than unity. Exce... View full abstract»
