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.

Soft-switching solid state transformer (S4T)
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016This paper presents a new topology for a fully bidirectional soft-switching solid state transformer (S4T). The minimal topology, featuring 12 main devices and a high-frequency transformer, does not use an intermediate DC voltage link, and provides sinusoidal input and output voltages. The S4T can be configured to interface with two-or multi-terminal DC,

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.

Noise adaptive soft-switching median filter
IEEE Transactions on Image Processing, 2001Existing state-of-the-art switching-based median filters are commonly found to be nonadaptive to noise density variations and prone to misclassifying pixel characteristics at high noise density interference. This reveals the critical need of having a sophisticated switching scheme and an adaptive weighted median filter.
