Todo lo que hay que saber para saberlo todo

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...

La historia secreta del nacimiento de la neurología. En sus inicios, los estudios sobre el cerebro humano seguían un método la mar de simple: esperar a que ocurriera alguna desgracia (derrames, infecciones, convulsiones, accidentes...) y observar cómo reaccionaban las víctimas. Los expertos quedaban maravillados al ver los cambios que tenían lugar dependiendo del punto del cerebro al que afectaba la lesión: padres que de repente no podían reconocer a sus propios hijos, hombres de conducta intachable que se convertían en mentirosos compulsivos o personas que perdían la capacidad del...
