Study on powering electric filters with unipolar high voltage pulses

Abstract

The article presents the devices of existing power supplies for electrical engineering installations and analyzes their disadvantages. The necessity of developing a method for stabilizing discharge processes in corona discharge electric fields is formulated. The calculation of the transient process in the pause between pulses when powered by unipolar high-voltage pulses with a duty cycle of more than 5 is carried out and the conditions under which the discharge currents are stable are determined. A source with two-way power supply and air cooling has been developed to supply electric filters with unipolar high-voltage pulses. The schematic diagram of the source of periodic voltage pulses, the parameters of the circuit elements, the device of the step-up transformer, the oscillogram of the voltage at the output of the generator and the type of voltage at the output of the source are given.
