New four-switches bipolar solid-state Marx generator

A novel solid-state modular topology capable of generating monopolar and bipolar high-voltage pulses is presented and discussed in terms of reliability for industrial applications. The novelty of this topology is that only four on-off switches are used per cell and the positive and negative pulses are produced using only one on-off switch per cell. Similar to other Marx topologies the main capacitors are charged in parallel and discharged in series, although the switches responsible for the application of negative and positive pulses into the load must hold-off twice the cell voltage. Simulation results for bipolar operation are presented.
