Commutation of high current pulse electric schemes using the inductance with a rectangular hysteresis loop

Two-electrodes commutator for power electric scheme switching is proposed and investigated at the following operation mode. Closing of high current scheme is realized by applying of high voltage low current pulse to commuted gap. By means of nonlinear inductance that separated the commutator and the main power capacitor storage element, the conditions were fulfilled at which nonlinear inductance had the high inductive resistance for triggering signal because of operating at the linear part of the hysteresis loop, but low one for the main power electric scheme at the saturation region. The tests of such system has been carried out at the power plasma gun working. The stored energy 100 kJ of 50 capacitors 150 /spl mu/F and 5 kV each was commuted by the triggering pulse of 10 sec triangular shape with voltage amplitude 30-100 kV and current up to 10 A.
