Well here the issue with the "EMP spell", For one it's never decribeded as such, it's more decribeded as a side affect of the magic in the area, not a specific spell, so this really can't be used as an argument for Voldemort as it's a side affect of the school grounds, not a magicical skill. So this "EMP" argument isn't a really valid argument for Voldemort.

Second Vader's lightsaber is powered by a force crystal and can only be shut off if it's connection to the force is cut off. amd Finally Vader has force technique that allows him to function without his suit for a limited time, so long as he has suffcient anger can can breath with out his suit.
