Abstract
A repetitive high voltage pulse modulator based on solid state switches with insolated recharge is described. All capacitors in the modulator are recharged by a corresponding transformer separately through magnetic core transformers by a common high frequency power supply. This configuration simplifies the isolation design and arrangement. This scheme is suitable for work at high repetitive rate discharge due to its high charge efficiency. At the same time it retains the inherent switch protection capability of a solid-state Marx modulator. In our present work, a 22-stage test modulator has been built and has been successfully operated at repetitive rate of 20kHz, output voltage of 20kV, rise time of 150ns and pulse width of 3μs. The primary experiments verified the system feasibility. A system with higher parameters is under way.
