Modified multistage semiconductor-Fitch generator topology with magnetic compression

For non-thermal plasma technology corona discharge devices high-voltage, high-current pulses are used with very high demands considering rising voltage slopes. Many solid state pulse power modulator (SSPPM) system topologies are known however most include a high power transformer compromising the overall system efficiency. A modified Fitch generator topology is introduced enlarging the output voltage to supply voltage ratio to theoretically the factor of three. Moreover the output voltage waveform enables the magnetic pulse compressor cross-section minimization with the factor of 0,67 due to a unique output voltage waveform. Test stand results are given for a 10-stage construction and a single stage magnetic compressor, power switch dynamic parameters influence on systems efficiency is discussed.
