Abstract

Un dispositivo de soldadura o de corte incluye un primer transistor que se acopla entre un primer nodo y un segundo nodo. El primer transistor controla la corriente y el voltaje que se proporcionan a un inductor durante una operación de soldadura o de corte. El dispositivo de soldadura o de corte también incluye un primer diodo que se acopla en serie con el primer transistor entre el segundo nodo y un tercer nodo, y un segundo diodo que se acopla en paralelo con el primer transistor y el primer diodo entre el primer nodo y un cuarto nodo. Además, el dispositivo de soldadura o de corte incluye un segundo transistor que se acopla en serie con el segundo diodo y en paralelo con el primer transistor y el primer diodo entre el cuarto nodo y el tercer nodo. El segundo transistor controla un voltaje aplicado a un transistor durante una operación de rotación libre del inductor. Además, el dispositivo de soldadura o de corte incluye el inductor dispuesto entre el segundo nodo y el cuarto nodo y acoplado a un primer terminal de una salida y un segundo terminal de la salida acoplada al cuarto nodo. Por otra parte, el dispositivo de soldadura o de corte incluye un condensador del bus que se acopla en paralelo con el primer transistor y el primer diodo entre el tercer nodo y el primer nodo.
