GENERATOR FOR STEEP-WAVE IMPULSE VOLTAGE

摘要

PURPOSE:To improve starting characteristics by a method wherein sphere gaps are short-circuited in succession by applying trigger pulses to trigger electrodes set up into the sphere gaps, and electricity is discharged through the sphere gaps connected in series multistage shape. CONSTITUTION:When trigger pulse voltage is applied to a trigger pulse terminal TR2 when the potential of a main capacitor C reaches the maximum of high- tension pulse voltage and electricity is discharged in the sphere gap G2 through a coil L for transmitting pulses, applied voltage of twice as large as other sphere gaps is also applied to the sphere gap G1 and electricity is discharged. Consequently, electricity is also discharged similarly in the sphere gap G3. As a result, a section between a high-tension terminal A and an output terminal B is short-circuited. Accordingly, the gap voltage of the sphere gap at the next stage is increased up to twice more by applying trigger pulses and discharging electricity in the sphere gap G2, the time lag of discharge time and the variance of discharge are reduced, and electricity can be discharged stably.
