Abstract :
Fast bipolar voltage pulses were generated for exciting a dielectric coated discharge system by using a nonlinear transmission line (NLTL) which included nonlinear capacitors. The energy transfer efficiency of a basic resonant circuit consisting of a nonlinear capacitor was evaluated from the viewpoint of efficient energy transfer. The simulation results of the pulsed laser discharge show that the nonlinear capacitor is effective both in increasing the peak voltage and shortening the pulse width. A bipolar voltage pulse was generated by a specially connected cable discharge system switched by an SI thyristor. The input pulse of 700 V, 130 ns(FWHM) was compressed to 1.4 kV, 30 ns (FWHM) at the 7th section. The N/sub 2/ gas was excited by these short pulses and showed light emission of 30 ns (FWHM).
