Multiport converters are used in interfacing of distributed energy sources with grid/load. Isolated needed applications where converter gain is high and there a requirement isolation. Dual transformer asymmetric triple active bridge offers the advantage reduced circulating current. However, operating range low for variation load source voltage.

A novel asymmetrical interleaved dc/dc switching converters family intended for photovoltaic and fuel cell applications is presented in this paper. The main requirements on such applications are small ripples in the generator and load, as well as high voltage conversion ratio. Therefore, interleaved structures and voltage multiplier cells have been asymmetrically combined to generate new conver...

A previous article has presented the members of the asymmetrical interleaved dc/dc switching converters family as very appropriate candidates to interface between photovoltaic or fuel cell generators and their loads because of their reduced ripple and increased current processing capabilities. After a review of the main modeling methods suitable for high-order converters operating, as the asymm...

An asymmetrical pulse width modulated (APWM) dc-dc converters operating at constant frequency was simulated using Pspice software package. This converter incorporates constant frequency operation in a basic soft switching half bridge topology without any additional component and complexity. In this paper operation of converter configuration with capacitive filter in the output is discussed. A 5...
