Analysis of soft synchronous commutations in switching converters
2000 IEEE International Symposium on Circuits and Systems (ISCAS), 2000 In this paper a new method for the analysis of soft synchronous commutations in switching converters is presented. The method is based on the application of the compensation principle, and allows one to perform jointly the analysis of both hard and soft synchronous commutations.

SOFT-SWITCHING PWM CONVERTER TECHNOLOGIES
Journal of Circuits, Systems and Computers, 1995The switched-mode power conversion technologies have evolved from the basic PWM converters to resonant converters, quasi-resonant converters, multi-resonant converters, and most recently, to soft-switching PWM converters. In this paper, several typical resonant techniques and several soft-switching PWM techniques are reviewed, and their merits and ...

Soft switching choppers: A study by the equivalent soft switching cell method
Canadian Journal of Electrical and Computer Engineering, 1990The switching cell concept was first introduced and used in order to study the micro-phenomena involved in the switching process; parasitics' influence, switching losses, snubbers, soft switching principle and so on. The authors demonstrate that the switching cell can also be a very efficient tool in the study of various converter topologies.

Analysis of switching-invariant characteristics of soft-switching cells
IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2002In this paper, a model representing the switching invariant properties of soft-switching cells is presented. On the basis of the application of the compensation theorem and of the adoption of the switching cell modeling approach, a cause-effect model of the behavior of six families of switching cells in hard and soft commutations is formulated.

Switching dynamics of IGBTs in soft-switching converters
IEEE Transactions on Electron Devices, 1995Next generation of power semiconductor devices will be designed and optimized to meet the specific application requirements. Mixed-mode simulations are used to study the carrier dynamics in punch-through and nonpunch-through Insulated Gate Bipolar Transistor (IGBT) structures during soft- and hard-switching conditions.

Research on Soft Switching Boost Converter
2011 Second International Conference on Digital Manufacturing & Automation, 2011This text introduce a sort of new soft switching Boost converter. The conventional Boost converter generates switching loss at turn on and off. So the whole system's efficiency is reduced. The proposed converter utiLizes soft switching method using an auxiLiary switch and resonant cirCuit.

A Single-Stage Soft-Switching AC/DC Converter without Soft-Switching Auxiliary Circuit
2019 IEEE International Conference on Industrial Technology (ICIT), 2019This paper proposed a single-stage soft-switching AC/DC converter without soft-switching auxiliary circuit. The proposed AC/DC converter only uses two main active switches to execute the input power factor correction and regulate the output dc voltage magnitude.
