Measurement of voltage rise curves due to gap discharge usingcoupled transmission lines in distributed constant line system

摘要

Very fast voltage rise curves due to gap discharge were examinedto discuss an EMI source. The measurement system consists of adistributed constant line system, because the voltage transients werevery rapid. A characteristic of the gap electrode, which has a matchedimpedance for the distributed constant line system, was investigated inthe frequency range below 5 GHz. The voltages of the power source in theexperiment were 510 V and 800 V because Paschen's law holds itsstability in the air condition. It was confirmed that the measurementmethod enables one to measure high speed voltage rise curves of about100 ps
