Devices and methods for preventing shock from a high voltage power source. In one embodiment, a device for preventing an electric shock, the device comprises output terminals for connecting to an external load, a low voltage circuit for carrying a first current (I L) to the output terminals, the low voltage circuit comprising a first coil disposed about a magnetic core, and a high voltage circuit for carrying a second current (I H) to the output terminals, the high voltage circuit comprising a second coil disposed about the magnetic core, and a control relay configured to electrically connect one of the high voltage circuit and the low voltage circuit to the output terminals based at least partly on the first current (I L).

Linvention concerne des dispositifs et procédés pour empêcher un choc dune source dalimentation de haute tension. Dans un mode de réalisation, un dispositif pour empêcher un choc électrique, le dispositif comprenant des bornes de sortie pour connexion à une charge externe, un circuit de basse tension pour porter un premier courant (IL) vers les bornes de sortie, le circuit de basse tension comprenant un premier enroulement disposé autour dun noyau magnétique, et un circuit de haute tension pour porter un second courant (IH) vers les bornes de sortie, le circuit de haute tension comprenant un second enroulement disposé autour du noyau magnétique, et un relais de commande configuré pour connecter électriquement lun du circuit de haute tension et du circuit de basse tension aux bornes de sortie en se basant au moins en partie sur le premier courant (IL).
