**Preface to "Design and Control of Power Converters 2019"**

In terms of research, power electronics is one of the most prolific fields in the world of electronics. One of the main reasons for this is its relevance for present-day society, which is increasingly concerned with energy-saving and greener energy production. This scenario constitutes a powerful catalyst for research, not only boosting the amount of interesting ideas, solutions, and studies, but also the number of topics that emerge under the umbrella of power electronics. This can be seen in the fact that well-established research topics as varied as renewable energies, battery management,

and electric traction coexist—or even merge—with more recent topics such as LED lighting or microand nano-grids. Moreover, these topics can be considered as established when compared to others like wide-band-gap devices and electric vehicles, where research is still incipient.

In all of the aforementioned topics, in addition to others, the "design and control of power converters" plays a key role. In this book, representative papers that focus on well-established topics, as well as more recent ones, can be found. This mixture will unquestionably foster new ideas for readers and will help researchers detect solutions that can be migrated from one topic to another, making this book a relevant milestone for any power electronics engineer.
