| Abstract: | The rep-rate wire-plane corona plasma generator experimental platform has been constructed. The platform consists of resonant charging circuit, pulse step up transformer, and magnetic switch for output pulse width adjustment. The platform can generate pulses with 150 kV peak voltage, 0.53 μs rise time, 1 kHz rep-rate and 5～25 μs adjustable pulsed-width. The paper describes the scheme of pulsed-transformer-type power modulator and output pulse-width adjustment. According to the analysis of experimental results, distributed capacitance of pulse transformer’s primary and secondary windings is the main factor affecting power efficiency. At last, this paper, gives out several critical points to improve this type of corona plasma generator. |
