Abstract
The present invention provides an electric fence controller for delivering an electrical shock to a load when the load simultaneously contacts a fence terminal and the underlying ground. In one embodiment, the controller comprises an AC power supply and a fence terminal positioned above underlying ground. The controller also contains a voltage step-up circuit coupled to the AC power supply for charging at least one multiplier unit and for producing at the fence terminal a substantially increased DC voltage. The at least one multiplier unit discharges as an electric shock to the load when the load contacts the fence terminal and the underlying ground.
