Abstract
As part of a pulsed corona system for pollution control applications, a high-voltage pulse generator was developed, constructed and tested. A 1kW generator delivers a 45kV, 100ns pulse across a 120Ω load with a risetime of 15ns and a repetition rate of up toi 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 2.5kA, 3kV 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 6kW pulse generator for an advanced industrial-grade system.
