Abstract

1,257,668. Pulse generators. EMIL HAEFELY & CIE. AG. 15 May, 1969 [17 May, 1968], No. 24765/69. Heading H3P. [Also in Division H2] In a Marx pulse generator or a surge diverter, each resistor 9 in a chain of resistors is connected across a corresponding spark gap in a chain of spark gaps, and adjacent electrodes 2...7 in the spark gap chain are capacitively coupled to opposite ends of the chain. By variation of the number of spark gaps or the value of capacitors 11, 12, the impulse ratio, i.e. the ratio of the flashover voltage under a voltage pulse to that under a steady D.C. or A.C. voltage, may be made as small as desired.
