A novel design scheme for the compensation circuitry of solid-state Marx modulators has been described for enhancing the compensation ability of the compensation cells of solid-state Marx modulators and simplifying the entire circuitry of the modulator. High-speed solid-state switches are adopted in the new compensation cell for the control of the compensation actions. Inductive components and diodes are adopted in the design scheme to smooth the flattop of the voltage pulse output by the Marx modulator.
