Compact high voltage solid-state pulse generator based on series RSD

The series Reverse Switched-on Dynistor (RSD) assembly drive technology based on integrating RSD switch and its triggering circuit was considered in this paper for the construction of a compact high voltage solid-state pulsed power generator which operated in a rep-frequency discharge mode. Firstly, RSD semiconductor reverse-triggering model was presented based on the element´s quasi-diode mode. An additional RSD serial resonance triggering circuit was set up. Based on this platform, direct-triggering experiments contributed to get the data used in the proposed model. Secondly, MATLAB simulation based on the Integration unit resonant triggering circuit and this RSD model was conducted. And the resonant parameters of 0.5Ω, 1.75μH and 0.2μF are derived under the requirement of RSD conduct current in main circuit, which set demands to charge of triggering carries injected in the pnn+ diode necessary for uniform RSD stitching. Furthermore, the additional product value of the voltage by the delay time caused by limited trigger resonant frequency must be taken into account during magnetic parameters design for saturated choke. Moderate Vt product on the core ensures the RSD triggering process completed in an accurate range of 2μs. At last, RSD triggering experimental results verify the reverse triggering model and resonant parameters. It is possible to implement a lOkV high voltage pulsed power generator utilizing series RSD unit.
