THE GENERATOR OF SHORT HIGH-VOLTAGE PULSES WITH INDUCTIVE ENERGY STORAGE WHICH IS COMMUTED BY SOS-DIODE

Using pulse electro-discharge technologies, including pulsed barrier discharge can achieve high performance in pu-rification of water from contaminating organic matters. To create an effective discharge, power sources of high-voltage pulses (10?30 kV) with steep fronts 1011?1012 V/s which length is 100-200ns are required. These parameters of pulse power supply can be achieved by using inductive energy storage which is commuted by SOS-diode. In practice, to im-plement effective joint operation of the power supply and the load which is like a discharge chamber with a non-linear active ? capacitive nature during the pulsed barrier discharge is a difficult task. That’s why, it was implemented a simu-lation of pulse generator loaded into a discharge chamber, which is conducting a barrier discharge, and including para-sitic elements of the discharge circuit. The reliability of the simulation was verified by comparing results with physical experiments. This makes it possible to determine the optimal parameters of the generator and the discharge chamber through simulation. It was determined the value for impedance of discharge chamber with a pulsed barrier discharge in which the rate of energy transfer from the pulse generator to them will be the greatest. This value of impedance dis-charge chamber is in a certain range of (~ 100?150 Ohm). For discharge chambers with impedance that is beyond these limits it is reasonable to attach the pulse transformer to the generator between it and the chamber.
