【Abstract】 A power supply that is able to generate fast-rise time and high frequency pulses is needed for plasma generator.A high-voltage and high frequency pulse sharpening circuit is designed according to the principle of magnetic switch technology and magnetic pulse compression technology.Pass through the circuit,the rise-time of the 5 kV and 5 kHz pulse is sharpened from 50 μs to 40 ns.The pulse sharpening technology and the design method of the magnetic switch are analyzed concretely.The PSPICE simulation model has been established,and simulation results show that magnetic switch can sharp the high-voltage and high-frequency pulses effectively.更多还原
