ФОРМУВАННЯ БІПОЛЯРНИХ ІМПУЛЬСНИХ СТРУМІВ У НАВАНТАЖЕННІ ЄМНІСНИХ НАКОПИЧУВАЧІВ ЕНЕРГІЇ ЕЛЕКТРОРОЗРЯДНИХ УСТАНОВОК.

A method is proposed for stabilizing the transient discharge processes of capacitive energy storages (CESs) of electric discharge installations (EDIs) to a load whose electrical resistance can vary non-linearly and stochastically. The method is based on the use of one direct voltage generator (DVG) in the EDI, which carries out alternately an oscillatory charge of two CESs to the required voltage, as well as on the introduction of semiconductor switches into the charge circuit and discharge one of these CESs and the developed algorithms for switching them on, according to which bipolar discharge currents are formed alternately in the EDI load, regardless of the nature of the change in its electrical resistance. The frequency and duration of positive and negative discharge-pulse currents in the load can be the same or different, depending on the selected parameters of the elements of discharge circuits of the two CESs. The use of the developed method provides the formation of unipolar modes in the capacitors of each CES, which allows you to choose them for lower voltages, increase their life and reduce cost. In addition, with the same capacitance of the CESs, the total electric charge flowing in the load is practically zero after each even number of discharges. This significantly reduces the effect of electrochemical processes in the load, in particular the electrochemical destruction of the anode of the technological apparatus of the EDI, which inevitably occurs during the formation of unipolar pulse currents. The use of bipolar discharge currents in the EDI load also increases the stability of the discharge modes in the EDI due to the limitation of the duration of possible long aperiodic currents during the discharge of one of the CESs by the beginning of the counter current of the next discharge of the other CES.
