In the electric discharge installations (EDI) with reservoir capacitors, in particular in the semiconductor (thyristor) installations for volumetric electro-spark dispersion (VESD) of the metals, the oscillatory discharge of capacitor with a small reverse recharge (less than 30 % in voltage) is the most efficient technologically and energetically mode of discharge through electric spark load [1-6].
The results of the analysis of the value ranges of the additional inductance [L.sub.2], which are required for the realization of the oscillatory discharge of the capacitor in the circuit with different load resistance, are given in Table.
Since the oscillatory discharge duration is proportional to the circuit inductance value, then in order to ensure short-term discharges, the appropriate values of [L.sub.2] should be minimum values from corresponding ranges: 103 [micro]H, 48 [micro]H, 15 [micro[H
This approach allows us to determine the range of values of such inductance for various load resistances in order to transfer aperiodic long-term capacitor discharge through the load in a short-term oscillatory discharge without solving a third-order differential equation.
If an oscillatory discharge of the capacitor through the load occurs and the capacitor is partially recharged to a reverse polarity voltage, then the negative feedback of the subsequent charge voltage of the capacitor with its previous discharge voltage is realized in the installation.
