Número de páginas: 215

 

 La electrónica es un tema muy extenso. En nuestra larga carrera como educador, orador en eventos y principalmente autor de libros y artículos técnicos escribimos cientos de miles de páginas sobre el tema y más de 150 libros publicados en diversos países. Una de las series de mayor éxito, adoptada en escuelas de diversos países es la denominada Curso de Electrónica que ya tuvo diversos volúmenes publicados en español como Electrónica Analógica, Electrónica Básica y Electrónica Digital en dos volúmenes. Hemos llegado a un nuevo volumen abordando un tema de extrema importancia en la actualidad con aplicaciones de la industria, automación, robótica, electrónica embarcada, aeroespacial y mucho más. Se trata de los semiconductores de potencia que consisten en una clase separada de componentes que necesitan un estudio apropiado por parte de todos los que los necesitan. Este volumen hace justamente eso, enseñando cómo funcionan los semiconductores de potencia de una forma simple directa, dando aplicaciones prácticas y los conocimientos básicos para aquellos que pretenden convertirse en ingenieros o proyectistas, con un avance en los cálculos que involucran su uso. Sugerimos que antes de la lectura de este volumen los lectores hayan obtenido previamente conocimientos básicos en los volúmenes anteriores citados arriba.
