This paper proposes solutions to increase the range of the voltage droop compensation needed to generate long pulses in the generalized solid-state Marx modulator. A novel design method based on the use of resonant circuits in generalized bipolar solid-state Marx modulator is described and evaluated. The increase of the compensation range is obtained by adding an extra auxiliary resonant stage to the existing Marx stages without changing the modularity of the circuit. The compensation is obtained by synchronously adding the voltages of the auxiliary compensation stages to the output voltage. Simulation results are presented for eight stages Marx circuit, ~17% voltage droop, using 6kV bipolar pulses, 100ps pulse duration and 50Hz repetition frequency.
