   Concept of 50kW DC/DC converter based on ZVS, Quasi-ZCS topology and integrated thermal and electromagnetic design
By DE HAAN Sjoerd; PAVLOVSKY Martin; FERREIRA Abraham [View]
[Download]

Abstract: A converter concept in the multi-kilowatt class with a high power density being the main goal is presented. High power density is achieved by implementing: ZVS, Quasi-ZCS topology and integrated thermal and electromagnetic design. ZVS, Quasi-ZCS topology reduces switching losses of IGBT switches and hence improves converter efficiency at high frequencies. Integrated thermal and electromagnetic design is used in high-power, high power density transformer which uses amorphous cores and foil winding technology together with heat pipes. A fully functional 50kW DC/DC converter (750V/600V) and a virtual converter prototype demonstrate the possibilities of the converter concept. High power density (up to 13kW/l without heatsink) and high efficiency (up to 97\%) are achievable by using the proposed converter concept.

   Experimental investigation of the Current Synchronized Control: Application to High Voltage/High Power DC/DC converters.

Abstract: In this paper, we present an experimental validation of a new control method for a ZVS hyper-resonant inverter as a part of a High Voltage/High Power DC/DC converter, called Current Synchronized Control. After a short reminder of its operation principle, we detail the implementation of a test bench for experimental validation. This bench enables us to identify practical considerations for its right operation and to compare it to a classical ZVS control mode.

   Rapid Design of LCC Current-output Resonant Converters
By BINGHAM Chris; STONE Dave; GILBERT Adam [View]
[Download]

Abstract: The paper presents and validates a straightforward design methodology for realising LCC current-output resonant converters, with the aim of reducing tank currents, and hence, electrical stresses on resonant components. The scheme is ideally suited for inclusion in a rapid iterative design environment e.g. part of a Graphical User Interface.
