摘要: 采用8只IXLF19N250A绝缘栅双极型晶体管串联研制成功了10kV固体开关。试验表明:该固体开关最高输出电压为14kV,最高输出脉冲电流为20A、输出脉冲宽度可在2~112μs之间以1μs步长变化,脉冲重复频率范围为1Hz~4kHz,短时间可以工作到8.6kHz。Abstract: A 10kV solidstate switch for high pulse power application has been developed. The prototype makes use of switches made of arranged in series. The output voltage can be adjusted from 1 to 10kV and the pulse width can be varied from 2 to 110 microseconds, the pulsing frequency in the initial design can be changed from 1Hz to 4kHz. Experimental results show that the solidstate switch can operate in the frequency up to 8.6kHz and in the voltage up to 14kV. The typical rise time is less than 300ns and the typical fall time is about 1.25μs.
