Abstract
Convertidor de alimentación conmutado a tensión cero comprendiendo una combinación serie de un primer devanado (11-3) y un primer elemento de conmutación (11-4). Un segundo devanado está conectado a un segundo elemento de conmutación (11-8) y una capacidad de almacenamiento (11-9), de modo que una combinación serie de una segunda capacidad de almacenamiento (11-8-1) y un tercer elemento de conmutación (11-8-2) está conectado en paralelo a dicho segundo elemento de conmutación (11-8) tal que cuando el segundo conmutador (11-8) entra en no conducción, el tercer conmutador (11-8-2) sigue en conducción comenzando un primer periodo de resonancia que finaliza cuando el tercer conmutador (11-8-2) entra en no conducción y comienza un segundo periodo de resonancia libre consiguiéndose la conmutación a tensión cero.
