Abstract：With the in-depth application of pulse power technology in wide range of biomedicine, food processing, electromagnetic forming, plasma generation, etc., it has posed new requirements to pulse generators such as high-volt high frequency, bipolar, and all solid state. Therefore, in this paper, a novel bipolar high-volt pulse generator circuit topology is proposed. Theoretical analysis, simulation and experimental results show that it combines the advantages of solid-state Marx and bridge circuits, which can realize high voltage output through simple stacking of modules, flexible output adjustment for polarity and pulse width by sequential logic control of the switch, and high repetition rate with long lifetime. The experimental prototype has been developed with characteristic parameters as follows: the output voltage amplitude is ±5kV, the repetition rate is 2.5MHz in the pulse train, and the pulse width is 200ns~10μs.
