Une bobine de fil de cuivre à auto-couplage de transformateur (4) est disposée dans l'enveloppe de protection (1), la bobine de fil de cuivre à auto-couplage de transformateur (4) comprend un noyau magnétique annulaire (4.2), et un enroulement de cuivre pur (4.1) qui est enroulé sur le noyau magnétique annulaire (4.2). Le transformateur d'utilisateur survolteur-dévolteur réglable à engrenages multiples à large gamme permet de pallier les défauts de l'état de la technique, a une conception raisonnable et une structure compacte et résout le problème qui se pose lorsqu'un appareil électrique ne peut pas être utilisé, lorsqu'il présente des pertes élevées ou lorsqu'il est endommagé en raison de la difficulté d'un stabilisateur de tension existant à ajuster des tensions inférieure et supérieure dans une gamme ultra-large; et grâce à une combinaison structurelle simple et à l'agencement d'un écran d'affichage de tension (6), une tension d'entrée peut être facilement vérifiée, un commutateur de changement de phase (2) est ensuite utilisé pour commuter des joints de fil de cuivre (4.3) avec différents rapports de nombre de tours, ce qui permet d'ajuster de manière pratique des tensions supérieure et inférieure en une tension de sortie nominale, d'améliorer la conversion d'énergie, de réduire les pertes, et d'obtenir un niveau de faisabilité élevé.
