Solid-state Marx Generator Design with an Energy Recovery Reset Circuit for Output Transformer Association

This paper presents a hybrid fully integrated solid- state Marx generator circuit, which has been developed for high-frequency (kHz), high-voltage (kV) applications needing rectangular pulses. The proposed circuit takes advantage of the intensive use of power semiconductor switches to increase the performance of the classical Marx circuit, strongly reducing losses and increasing the pulse repetition frequency. In addition, to further increase the output pulse, the proposed topology is enhanced with an energy recovery reset circuit that enables the use of an output pulse transformer, and recovers the transformer magnetizing energy, during the pulse off state, back to the energy storage capacitors.
