Investigation of a compact solid-state Marx generator

  • 摘要: 提出利用P型开关作为充电管、N型开关作为放电管串联形成半桥结构,将其门极也短接,以同一个信号同时驱动充电管和放电管。再利用共原边的串心磁环驱动方案,只需一个半桥电路就可以从原边同时传递驱动功率和信号,同步驱动所有充电管和放电管,大幅简化了脉冲电源结构和尺寸,降低了成本。以此搭建了24级固态Marx发生器,在10 kΩ阻性负载上,获得了10 kV、1 kHz、5 μs的高压方波脉冲,验证了方案的可行性,该电源主电路的尺寸仅为20 cm(长)×13 cm(宽)×5.5 cm(高)。
