Based on Generalized switchingcell approach, a generalized state-plane analysis for families of soft-switching dc-to-dc converters will be presented. It is shown the analysis of soft-switching dc-to-dc converter families can be analyzed in terms of simple two-dimensional state-plane diagram. Complete generalized design equations will also be given. It will be shown that one generalized transfor...

— The design of an efficient monolithic buck converter is presented in this paper. A low swing MOSFET gate drive technique is proposed that improves the efficiency characteristics of a DC-DC converter. A model of the parasitic impedances of a buck converter is developed. With this model, a design space is described which characterizes the integration of both active and passive devices of a buck...

The purpose of this paper is twofold. On one hand, basics on switched circuits for designing a DC-DC converter are presented and, on the other hand, power electronics definitions associated with simple electrical networks are mentioned. In the analysis of these networks, it is necessary to take into account not only converters’ non-idealities but also how to minimize power losses. Since power l...

A method for designing power line filters for SMPS is presented. The practical design work is optimized, by excluding the nonviable combinations of filter components. The designer can choose among the theoretically viable combinations, to try practical designs. The theoretical calculations are based on chain parameters. As an illustration of the method a single stage π-filter for a buck convert...

In recent years, more research has been done on Enhancement Mode Gallium Nitride (eGaN) converters as the world is moving towards more power efficient converters. The process to make converters more efficient was bit complicated and slow in 20th century. With help of simulation tools such as MATLAB and LTspice, this process has become much faster and reliable in modern era. In order to make thi...

Ideal power converters are governed by differential equations with discontinuous right-hand sides. General-purpose algorithms to compute their Lyapunov exponents assume smooth equations, so are not directly applicable to power electronics. We review the methods and their problems, focusing on the largest Lyapunov exponent, which dominates system behavior. The variational approach can incorporat...

Switched circuits in power electronics by their nature present hybrid behavior. Such circuits can be described by a set of discrete states with associated continuous dynamics. A control objective, usually regulation of the output in the face of disturbances in the continuous system, is accomplished by choosing among discrete states. We describe a hybrid systems perspective of several common tas...

Dc-dc converters suitable for use in battery-powered electronic equipment with energy management are discussed. To realize the benefits of energy management, these converters must be capable of maintaining regulation of their output voltages at no load, while maintaining high efficiency. Variable frequency operation is shown to give an improvement in efficient operating range of approximately t...

In this paper, a novel high step-up DC-DC converter with coupled-inductor and voltage-doubler circuits is proposed. The converter achieves high step-up voltage gain with appropriate duty ratio and low voltage stress on the power switches. Also, the energy stored in the leakage inductor of the coupled inductor can be recycled to the output. The operating principles and the steady-state analyses ...
