A full-bridge CLLL DC/DC converter that uses an auxiliary circuit is proposed in this paper. The soft switching of lagging leg and auxiliary switches is achieved by the proposed circuit for providing reduced switching losses and high efficiency. The theoretical detail operation of the converter is presented. The proposed converter is verified using MATLAB(More)
With the increasing growth of technology and the entrance into the digital world, we have to handle a enormous amount of information every time which often presents difficulties. So, the digital information must be stored and retrieved in a professional and valuable manner, in order for it to be put to practical use. Imaging requires large amount of memory(More)
ECG is the generally recognized biomedical signal for diagnostic purpose and it shows the electrical activity of the heart muscles. ECG is a non stationary signal where wavelet transform (WT) is useful for analyzing it. Denoising is the process of removing noise in order to preserve useful information. A comparative analysis of various wavelet shrinkage(More)
Fingerprint is the unique way of identification, but still the application of fingerprint identification is overlooked because of its large storage capacity of the data. Due to which the technique of data compression has been introduced to reduce the storage of image. In this paper, bi-orthogonal wavelets are used for compressing the image and determine the(More)
