Switching-invariant models of soft-switching cells
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002 In 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.

Soft Switching in Switched Inertance Hydraulic Circuits
BATH/ASME 2016 Symposium on Fluid Power and Motion Control, 2016 Switched Inertance Hydraulic Systems (SIHS) use inductive, capacitive, and switching elements to boost or buck a pressure from a source to a load in an ideally lossless manner. Real SIHS circuits suffer a variety of energy losses, with throttling of flow during transitions of the high-speed valve resulting in 44% of overall losses.

Soft switching converter with powerlimiting feature
IEE Proceedings - Electric Power Applications, 1999 A new zero voltage, soft switching converter is presented. This converter implements ZVS to minimise switching losses and it has special output power limiting characteristics. At a constant switching frequency the output power is limited to a maximum value and power falls at high current and low current.

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.

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 ...

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.
