A novel control principle of bi-directional DC-DC power conversion
PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 2002This paper presents a novel control method for DC-DC power converters with bi-directional power flow and galvanic isolation. A high efficiency is achieved by using a minimal number of power electronic devices working in the soft switching mode. No reverse blocking switches are required.

Boost building block (B/sup 3/) [DC/DC power conversion]
21st International Telecommunications Energy Conference. INTELEC '99 (Cat. No.99CH37007), 1999This paper presents a method of integrating a boost converter. The basic idea is to integrate all the semiconductor devices and the snubber circuits on a ceramic substrate with an automated assembly process. This integration results in a more compact packaging of the boost converter with a better thermal performance.

Bidirectional DC/DC power conversion using constant frequency multi-resonant topology
Proceedings of 1994 IEEE Applied Power Electronics Conference and Exposition - ASPEC'94, 2002A family of bidirectional DC/DC converters is proposed using the constant frequency zero-voltage switching (ZVS) multi-resonant topology. This family of converters provides ZVS operation of all semiconductor devices from no-load to full-load while achieving full DC conversion ratio range, and has inherent short-circuit protection capability.
