Analysis of ZVS non-isolated bidirectional DC-DC converter
2011 IEEE 54th International Midwest Symposium on Circuits and Systems (MWSCAS), 2011This paper mainly focuses on the development of high efficiency non-isolated bidirectional DC-DC converter with large voltage diversity. The proposed converter can operate with soft switching using a technique of zero-voltage switching (ZVS). Coupled-inductor and voltage clamped circuit with only three switches, operating in synchronous rectification ...

Two Switch Non-Isolated Quadratic Gain DC-DC Converters
2020 Third International Conference on Smart Systems and Inventive Technology (ICSSIT), 2020Different types of DC-DC converters are widely used in applications like fuel cells, electric vehicles and to transfer renewable energy, which is a low voltage, to different loads. In high voltage applications, these DC-DC converters are not appropriate due to low gain.

An improved Non-Isolated Multiple-Input buck dc-dc converter
2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC), 2017In this paper, an improved Non-Isolated bidirectional Multiple-Input (MI) Buck dc-dc converter has been proposed. In the proposed topology, the input sources can simultaneously/independently transfer energy to the load. The applied energy storage system -battery- not only realizes the bidirectional power flow (even when none storable input sources like

Analysis of Non-isolated Soft Switching DC-DC Buck Converter
2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems, 2008A novel zero-voltage switching (ZVS) step-down converter with a tapped inductor is proposed in this paper. Tapped inductor provides better power density as compared to isolation buck converter. With a simple structure, the tapped-inductor buck converter shows promise for extending the duty cycle. This converter is cost effective and attractive for high
