Terascale physics is driving the demand for innovative pulsed power modulators having greater compactness and better manufacturability with increasingly superior performance. A particularly promising route for such modulators is Marx-architecture based. Moreover, there is opportunity for improvement and gain of greater benefits through further development of topology and architecture, gate driver method, and control schemes. Prior work discussed a new concept of droop correction, which was the result of topology hybridisation using a nesting approach, and illustrated its great potential. This is further investigated here. This paper details various design aspects of a hybrid Marx cell Power Electronic Building Block (PEBB) and includes specifics about estimated losses and efficiency, thermal management issues, protection strategies, gate driver development, and control implementation. In addition, figures-of-merit of the cell design are given for comparison and evaluation purposes. Experimental results, based on both single-cell and three-cell hardware prototypes, are presented demonstrating the functionality and performance of the new topology. This is a significant milestone in the progression toward constructing a full 32-cell PEBB-based Marx klystron modulator with nested droop correction. Lessons learned during various stages of the prototype development and future directions are commented on.
