摘要：
High-frequency nanosecond pulsed discharge is an effective way to generate non-equilibrium plasma for plasma assisted ignition and combustion research. In this paper, a compact high-frequency nanosecond-pulsed ignition system is designed based on resonant charging and magnetic pulse compression. Details of the electrical architecture and working principles of the ignition system are presented. The system can produce high voltage pulses over 10 kV, with a rising time of 20 ns, and a full width at half maximum of 50 ns, at repetition rate up to 16 kHz. Test results show that 10 pulses at repetition rate of 16 kHz have larger discharge volume and higher brightness than single pulse, and the utilization of coaxial electrode enlarges the discharge volume compared with pin-to-pin electrode. The experiment results show that the ignition delay time of multi-pulse discharge is much shorter than that of single-pulse discharge, and coaxial electrode discharge can significantly shorten the ignition delay time compared to pin-to-pin electrode with the same pulse number. © 2021, Jilin University Press.
