HIGH-VOLTAGE PULSE GENERATOR

摘要

FIELD: high- voltage pulse engineering. SUBSTANCE: generator has grounded electrode forming short-circuited stepped line at input set up of series-connected sections of homogeneous lines with distributed parameters of equal electric length. Inner space of first section of stepped line accommodates high-voltage electrode that separates it into two homogeneous lines. Voltage supply and spark gap are inserted between high-voltage and grounded electrodes; spark gap is placed at joint between first and second sections of stepped line. Parallel-connected resistive load and current chopper are provided at stepped line output. Inserted in series with grounded electrode are parallel-connected current supply and spark gap. Wave impedances of lines formed by high-voltage and grounded electrodes in first section of stepped line are chosen from proposed equation. Generator is characterized in that pre-pulse voltage across generator output is eliminated and bulk of energy is stored in generator in the form of magnetic field. EFFECT: improved efficiency of square pulse across resistive load whose voltage is much higher than generator charging voltage; reduced requirements to electric strength of generator due to full energy storage. 1 dwg øøø1
