ABSTRACT:
A ground-free device for removing static charges from semi-conductive or conductive bodies. The device includes a storage capacitor, a conductive contact connected to the storage capacitor, and an air capacitor connected to the storage capacitor, in which a voltage below the breakdown voltage of the air is imposed on the air capacitor, e.g., by an RC-controlled transistor oscillator circuit. The device provides high efficiency removal of static charge, e.g., from the metallic bodies of cars and aircraft.
