Compact repetitive Pulsed E-field Generator

Provided with the advantages of long life time and high-repetition frequency, the pulsed power generator based on the Semiconductor Open Switch (SOS) has a promised prospect in the civil application. Compact repetitive Pulse E-field Generator is developed for the research of bio-effect. The generator is comprised of two parts: the pulse generator SPG50 and the parallel-plate transmission lines. The pulse generator is based on SOS and designed to deliver high voltage pulses to transmission lines. The pulsed E-field which is formed in transmission lines could be used for bio-effect. The generator can be operated on two modes; a Emax=104kV/m,FWHM=89ns,trise=40ns,repetition frequency 100Hz; b Emax=86kV/m, FWHM=15ns, trise<6ns,repetition frequency 1Hz. © 2008 Institute of Fluid Physics, C.
