A method and apparatus for using an arc-dipole in an opening switch to generate a power pulse to a load from a storage device. A power pulse is delivered to the load over a time which is short as compared to the energy storage time. A magnetic field may be used to enhance the arc-dipole and thereby shorten the opening time. A pulse-voltage source is imposed across the electrodes or spark gap in order to form and then extinguish the arc dipole. Preferably, a pre-charged capacitor may be used as a source for the pulse current. When the arc dipole is extinguished, charged particle free spaces are formed around the surface of the electrodes which serves as a reliable dielectric thereby inhibiting re-ignition. The invention may be used to produce pulses to a load at a repetition rate on the order of about 1 to 1,000 bps. |
