Design of a semiconductor-based bipolar Marx generator

For parametric studies on the electroporation of plant cells a pulse source enabling a waveform generation within a wide parameter range is of advantage. Hence, a semiconductor-based bipolar Marx generator has been designed. IGBT switches have been employed. Switches and control circuitry enable individual stacking of stages to generate stepwise arbitrary waveforms. The paper compares different configurations of semiconductor-based bipolar Marx generators and describes the design of the Marx generator.
