Method and device for reducing the ignition voltage of power pulses pulsed plasmas

摘要

When using powerful pulsed plasmas, it is often necessary for technological reasons, the length of the pulse - from - time to vary. An extension of the pulse - from - time, it is possible in this case to an increase of the ignition voltage of the following pulse, which the demands on the power supplies increased. The new method is intended to a significant extension of the pulse - from - time, without that it comes to a rise in the ignition voltage. Dollars a by maintenance of a weak additional plasma discharge, which, during the pulse - - time of at least so many produces charge carriers, the ignition voltage of the following pulse always only a little above the operating voltage is, according to the invention, a growth of the ignition voltage with an extension of the pulse - from - time avoided. Dollars a plasma-enhanced coating methods.
