Abstract
The paper analyzes the interdependent transient processes in the discharge circuits of a bipolar discharge pulse generator (DPG) with R-L-C load and limited positive voltage feedback. The analytical dependence of the value of the initial voltage on the capacitor connected in series with the load on the value of the Q factor of the discharge circuit of the DPG was obtained. The optimal electrical parameters of these circuits have been determined to ensure high dynamic and energy indicators of impulse currents in an electric spark load. It is substantiated that the serial connection of a capacitor with an electric spark load in the discharge circuit of a bipolar DPG with a capacitive storage of electrical energy of high energy capacity allows to increase (maximum twice) the initial rate of current rise in the electric spark load of a bipolar DPG and significantly improve the energy indicators of discharge impulse currents. The short-circuit currents value of the DPG load is limited by the value of the characteristic resistance of the DPG discharge circuit, and their flow time corresponds to the self-oscillation period of the DPG discharge circuit in this mode of operation. At the same time, electrical energy is not dissipated in the discharge circuit of the DPG, but it is almost completely recovered to the capacitors on output of direct voltage formers.
