【 摘 要 】

The proposed solution makes possible the transfer of high-voltage excitation pulses through the long coaxial cable with the minimum losses and the excilamp efficiency. Use of resonant topology of the pulse converter provides ZCS at switching-ON and ZVC at switching- OFF of the transistors. The values of efficiency of radiation of ∼ 9% at the feedline of 2.5 m in length obtained during the experiments are about twice as much as the efficiency at the XeCl- excilamp excitation by the quasi-square pulses power supply due to the decrease of losses at switching and the increase of electric efficiency of a resonant power supply with the long coaxial feedline.
