Backward adaptive pixel-based fast predictive motion estimation [PDF]

, 2009
This letter presents a novel backward adaptive pixel-based fast predictive motion estimation (BAPME) scheme for lossless video compression. Unlike the widely used block-matching motion estimation techniques, this method predicts the motion on a pixel-by ...

Design and Implementation of an AC–DC Single-Switch Driver Circuit for Full-Spectrum LED Horticultural Lighting Applications

IEEE Access
Full-spectrum horticultural lighting combines broadband white light emission with complementary narrow-band components (including blue, deep red, and far-red light), simulating sunlight while maintaining the high performance of solid-state lighting and ...

An interleaved high step‐up DC–DC converter based on coupled‐inductor

IET Power Electronics, Volume 17, Issue 3, Page 473-485, 19 February 2024.
This paper proposes an interleaved coupled‐inductor high step‐up direct current (DC)–DC converter. The proposed converter has benefits such as low voltage stress across semiconductor elements, high voltage gain, and continuous input current which makes it suitable for applications such as renewable energy sources.

Energy methods for lossless systems using quadratic differential forms

, 2008
In this thesis, we study the properties of lossless systems using the concept of quadratic differential forms (QDFs). Based on observation of physical linear lossless systems, we define a lossless system as one for which there exists a QDF known as an ...

A polynomial approach to the realization of J-lossless behaviors

, 2010
We consider the problem of realizing lossless behaviours with respect to the supply rate equal to the scalar product of the input and of the derivative of the output variables.

Lossless passive snubber for half bridge interleaved flyback converter

IET Power Electronics, 2014
Discontinues output current of regular flyback converter will cause several problems such as large volume of output capacitor and also high output voltage noise. Interleaved structure can reduce output current ripple and process more power compared with single‐phase flyback converter.

Improved passive lossless turn-on and turn-off snubber

, 1993
An improved passive lossless turn on/off snubber is proposed where energy trapped in the snubber is transferred to both the DC rail and the load. A wider operational range of load current, a higher switching frequency and lower peak switch current make ...
