A high-efficiency bidirectional non-isolated multi-input converter
2016 19th International Symposium on Electrical Apparatus and Technologies (SIELA), 2016A high-efficiency bidirectional non-isolated converter with multiple input sources is presented in this work. In the proposed converter, the energy from/to the input sources is transferred via the coupled inductors connecting to a switch pair. This topology does not only allow active power sharing, but also results in reduced component count.

A Wide Output Non-Isolated Boost-Buck Converter
2019 4th International Conference on Intelligent Green Building and Smart Grid (IGBSG), 2019With the rapid development of new energy power generation, energy storage, electric vehicles and microgrid, the DC voltage generated by single power source is relatively low in the process of power conversion. It is necessary to add a DC converter at the front end of the system to improve the utilization rate of DC voltage.

Non isolated Boost converters with Switched Inductor Technique
2011 International Conference on Signal Processing, Communication, Computing and Networking Technologies, 2011This paper proposes three simple Boost structures which is based on Switched Inductor Technique (SIT) and Voltage Lift Technique (VLT). Compared with the existing methods, the proposed method achieves high voltage gain without an extremely high duty ratio.

Paralleling non-isolated multi-phase PWM converters
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002In paralleling converters, it is desirable to have a directly connected structure because of compact size, low cost, simplicity and easy expandability. However, the parallel converters may have interactions due to their nonisolation. This paper develops an average model of the parallel converters in rotating coordinates.

A multi-port converter topology with simultaneous isolated and non-isolated outputs
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013DC based Nanogrids are being increasingly implemented in modern residential applications for realizing smarter and greener energy efficient systems. The total power requirement for these applications can be realized by small localized generation systems (typically, renewable sources), which serve a wide variety of consumer loads.

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

Three-Phase Non Isolated Interleaved Boost Converter
i-manager's Journal on Power Systems Engineering, 2013Renewable energy sources, such as photovoltic cell and fuel cells, have quite low voltage output and require series connection or a voltage booster to provide enough output voltage. High step up gain, high efficiency and non -isolation are the main characteristics for these applications[13]-[17].

Non-isolated high-step-up resonant DC/DC converter
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016A non-isolated high-step-up resonant DC/DC converter made up of a resonant inverter and a passive switched-capacitor (SC) rectifier, is proposed in this paper. The proposed converter is free of transformer and coupled-inductor. Thus, issues related to the leakage inductance and the large volume magnetic component caused by large turn's ratio of high ...
