Abstract
A remote receiving circuit for providing and controlling an electric stimulus applied to an animal including an electronic switch powered by a battery in series on a primary of a high-voltage transformer and whose on/off state can be modified by control pulses to create a source of alternating current to supply the primary of the transformer. The circuit further includes a first electrode and a second electrode configured to be in contact with the animal and connected to the respective ends of a secondary of the transformer, and a device for measuring the peak intensity of a stimulus current applied by the electrodes to the animal's body.
