The authors present designs and analyze a pulsed power system to drive an intense plasma radiation source (PRS). The basic element of the design is a linear inductive voltage adder similar to HERMES III which provides the high voltage of 8--10 MV. The maximum output current of a practical voltage adder (module) is of the order of 2 MA. Higher output currents can be obtained by connecting a number of modules in parallel through convolutes to a common PRS load. This approach offers the flexibility of current variation by varying the number of modules connected in parallel as well as voltage variation by changing the number of cavities per module. If the required current is large, many modules must be connected in parallel. Because of their dimensions, the adders cannot be brought close to the load; therefore, long extension MITLs are required to transfer the power from the voltage adder to the load. In this paper the authors concentration on the design and analysis of a voltage adder module coupled to an inductive load. Parapotential flow and pressure balance models were utilized for the design supported by extensive circuit model code work and numerical simulations.
