Issues with electric fences in snow is that the ground is not good enough. A ground wire strung along the lower half of the fence line will look after that.
AC vs. DC -- I use a DC charger and have never had a issue with not enough charge. I have about 3 acres fenced in and the wire is all over the place. Ie. Not square fields. Lots of underbrush, etc. No problems unless a bear runs through the fence :)
Might want to recheck your science books Water is not a conductor. Pure water has an extremely high resistance. It is the minerals and salts that ionize in a water solution that cause it to conduct. This is 3rd grade science project stuff here, Infact it was my 3rd grade science project. A battery, some wire a bowl of water and a flashlight bulb, put the wire in the bowl of distilled water, No light. Add some salt light comes on.
Basic electricity here.
I have no idea how much mineral content is in snow though.
"A" DC charger... How many joules ? How much wire? What type of terrain Have you ever actually tested the current in the wire with all this brush you mentioned ? DC chargers that use a deep cycle car battery sized battery can do the job but do you really wanna be hauling 70lb batteries back and forth to recharge them ?
High tension cable will get your job done and deer and bears can't break it.
