Pasture fence device

Abstract

A pasture fence device is proposed with two independent storage capacitors, which can, by means of a switching element, be discharged through the primary winding of a transformer in order to produce a HV pulse. The second storage capacitor serves to increase the pulse energy. The inventive pasture fence device is intended to ensure that the output voltage is always sufficiently high to trigger a herding shock, while keeping the energy consumption as small as possible. The invention accomplishes this by providing a second switching element (THY 2 ) to control the charging process of the second capacitor (C 2 ).
