Abstract
On the basis of transient analysis of the oscillatory and aperiodic discharges of the reservoir capacitor of electric discharge installations on the load, it is shown that an increase in its capacitance reduces the duration of the rise of the discharge current from zero to any fixed value less than the maximum value of the current. Based on this, it is proposed the method for increasing the rate of rise of pulsed currents in the load, which is founded on increasing the capacity of the discharged capacitor and forced interrupting the current in the load when a specified fixed value (or duration) of the current is reached. Forced limitation of the discharge duration is carried out by a fully controlled semiconductor key. This is the actual method, in particular in electric discharge installations for the production of dispersed electro-eroded powders, since it allows to reduce their sizes. Two ways to implement the method are offered. References 14, figures 3, table 1.
