This thesis (written in Spanish) presents the analysis, design and implementation of a four-quadrant power supply with high-frequency isolation, which is expected to be used to feed the low-energy correction magnet of a particle accelerator. In particle accelerator applications the magnetic field during beam acceleration may be either positive or negative, and true bipolar power converters are needed. The selected bipolar topology consists of a bidirectional three-phase to single-phase reduced matrix converter (RMC) with power factor correction and a bidirectional active rectifier. Main...

Physics I: The Gymnasium of the Mind provides undergraduate students with a valuable opportunity to acquire the knowledge and the abilities that are evaluated in the PISA project (Program for International Student Assessment) and will be indispensable in later professional and personal life. The objective of this book is to use carefully analyzed and selected phenomena and adequately designed didactic activities to enable students to become involved and discover that they can learn physics, and with the knowledge and abilities learned, allow them to grow intellectually, emotionally, and...

Este libro es el resultado de la compilación de trabajos periodísticos aparecidos en la revista Alma Mater entre el 2009 y el 2013, dedicados al tema de la divulgación de los procesos científico-tecnológicos * hechos en Cuba* , fundamentalmente. En un inicio aparecieron en la sección LQQD ?casi siempre en la página 12, en su formato tabloide?, que la revista proponía a la divulgación de la ciencia y la tecnología en cualquier parte del mundo y de la cual se encargó el autor a principios del 2009. Sin embargo, ante la imposibilidad de sustraerse a la realidad que ofrece el...
