摘要：
The method of using magnetic switches is proposed to reduce the voltage rise time of the all solid-state pulse source and a generator is constructed. This generator consists of a Marx modulator based on isolated gate bipolar thyristor(IGBT) half bridge modules and a magnetic pulse sharpening circuit, which is employed to compress the rising edge of the Marx output pulse. The approach of using multiple small driving transformers, one-turn primary windings of which are in series connection, provides a simple way for gate drive. Coaxial cables are employed as both primary and secondary windings of these transformers for electro-magnetic interference(EMI) shielding. A passive over-current protection measure is adopted so as to promise safe operation of the discharging IGBTs. The experimental results show that the rise time of the Marx output pulse is reduced from 1.5μs to 200 ns under the condition of 10 kV and 170 A, and the single IGBT turn-on loss is reduced from 10 mJ to less than 1 mJ. The design of IGBT drive circuits and magnetic switches is introduced in detail in this paper.
