| Abstract: | The article introduces principle of four channel high voltage pulse power, and design of trigger and control based on photo electricity signal. Design a high voltage pulse power that output voltage amplitude is varied between 0.5kV-1kV, pulse width is more than 500ns, pulse raising-time is less than 25ns, and time difference is less than 10ns on each channel. The former photo electricity trigger pulse drives the latter high voltage semiconductor device IGBT that conducts current and outputs high voltage pulse. the result of experiment validate principle and method, and display four channel output pulse waveform on signal trigger. |
