DOI: 10.1007/978-3-642-28255-3_44 In book: Technological Innovation for Value Creation, Edition: 1, Chapter: Solid-State Bipolar Marx Converter with Output Transformer and Energy Recovery, Publisher: Springer Berlin Heidelberg, Editors: Luis Camarinha Matos, Ehsan Shahamatnia, Gonçalo Nunes, pp.403-410
The purpose of this paper is to present and discuss a general HV topology of the solid-state Marx modulator, for unipolar or bipolar generation connected with a step-up transformer to increase the output voltage applied to a resistive load. Due to the use of an output transformer, discussion about the reset of the transformer is made to guarantee zero average voltage applied to the primary. It is also discussed the transformer magnetizing energy recovering back to the energy storage capacitors. Simulation results for a circuit that generates 100 kV pulses using 1000 V semiconductors are presented and discussed regarding the voltage and current stress on the semiconductors and result obtained.
[Show abstract][Hide abstract] ABSTRACT: This paper reports the development of a stacked MOSFET switch with
a uniformly distributed magnetic structure to coherently deliver 45-ns
rise-time pulses from a 25-kV power supply. Gate jitter problems were
avoided. This circuit is currently in use delivering variable-width
50-kV pulses for an electric field generator. These fields are applied
to dry food samples at up to a 300-Hz repetition rate using oppositely
biased floating MOSFET stacks for simultaneous switching of two 25-kV
