Realization of subnanosecond power conditioning by using transmission line charging technique

The wave process and principle of the transmission line charging in impedance matched and mismatched condition are analyzed. The results show that the impedance mismatched charging technology can realize the power gain but lower the energy efficiency, while the impedance matched charging technology can obtain an energy transmission efficiency of 100%, but can’t realize the power gain. The radiation fields of the 5 W charged transmission line with length of 30, 45, 60 mm are studied experimentally, using 27 W charging transmission line, which is 540 mm long. A output pulse with risetime about 210 ps and peak voltage about 150 kV is obtained on the 5 Ω charged line, which is 45 mm long. The radiation electric field increases a little as the length of the charged transmission line increases
