This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...

In this paper we present a study of an emergency lighting system is not permanent. This system consists of batteries, LED boost converter and power. The focus of the paper is to analyze the boost converter, which employs ...

A new modulation strategy that allows operating the dual active bridge (DAB) dc–dc converter under soft switching in the whole operating range is proposed. This strategy is ruled by imposing a certain modulation index in ...

A switching control strategy to control the power flow and minimize the total power losses of the dual active bridge converter topology is proposed in this paper. The control strategy consists of driving the bridge with ...

High voltage direct current (HVDC) transmission systems and low voltage direct current (LVDC) networks are becoming popular due to their advantages and present feasibility, mainly pushed by the advance in power electronics. ...

The rise of new dc technologies is pushing the development of highly efficient dc-dc converters, especially at high voltage and high step ratio. Modular multilevel converters (MMCs) are an attractive alternative because ...
