Abstract :
As part of a pulsed corona system for pollution control applications, a high-voltage pulse generator was developed, constructed and tested. A 1 kW generator delivers a 45 kV, 100 ns pulse across a 120 Ω load with a risetime of 15 ns and a repetition rate of up to 1 kHz. It comprises of a single magnetic compression (MC) stage which incorporates both amorphous metal and ferrite cores for fast magnetic switching. The compressor does not contain external remagnetization circuits that are commonly used in magnetic compressors. A fast semiconductor ABB A-Z switch specified for 2.5 kA, 3 kV is used as the main switch. A thorough theoretical analysis of the circuit topology is presented. Experiments with a dummy load showed a fair agreement with simulations. Typical voltage and current waveforms, volt-ampere characteristics and the corona discharge appearance are presented. The results of this study are used for developing a 6 kW pulse generator for an advanced industrial-grade system.
