Asymmetric snubberless current-fed full-bridge isolated DC-DC converters

Thermal Management of High-Current Bidirectional Isolated DC-DC Converters

To my family i ACKNOWLEDGMENTS The research presented in this thesis was conducted at Delft University of Technology, the Netherlands, in the Electrical Power Processing (EPP) group headed by Professor Braham Ferreira. This is the place where I spent six memorable years towards my Master and Ph.D. degrees. Many people have been involved during this time and this thesis would not be completed wi...

Isolated DC-DC Converters with High Current Capability

Current-Sensing Techniques for DC-DC Converters

Current sensing is one of the most important functions on a smart power chip. Conventional current-sensing methods insert a resistor in the path of the current to be sensed. This method incurs significant power losses, especially when the current to be sensed is high. Lossless current-sensing methods address this issue by sensing the current without dissipating the power that passive resistors ...

Hybrid Renewable Resource Based Full Bridge DC-DC Converters For Static Load Applications

In Environmental friendly solutions are becoming more eminent than ever as a result of concern regarding the state of our worsen planet. This paper presents a modeling of solar and fuel cell hybrid isolated full bridge converter for electric vehicle driving system. The HFT (high frequency transformer) initiate in isolated full bridge boost converter for precipitate power conversion of photo vol...

Current - Fed Multi - Resonant DC - DC Converter *

A novel topology, Current-Fed MultiResonant DC-DC Converter (CF-MRC) was studied theoretically and experimentally. The main features of the proposed converter are an inherent protection against a short circuit at the output, a high voltage gain and zero voltage switching over a iarge range of output voitage. These characteristics make it a viable choice for the implementation of a high voltage ...
