| Keywords: Blumlein transmission line animation.gif Blumlein transmission line pulse generator an electrical circuit which produces very short current pulses used in pulsed power devices such as lasers particle accelerators and high voltage insulation testers The advantage of the Blumlein circuit is that its output voltage is equal to the power supply voltage V while a simple charged transmission line generator shown in companion file File Charge line animation gif has an output of V/2 The Blumlein consists of two transmission lines in series with the load Z<sub>L</sub> between them The lines are charged by a high voltage DC power supply attached to one end left A switch short-circuits the line at the power supply end creating a voltage step which travels toward the load Since the load Z<sub>L</sub> is twice the characteristic impedance of the line Z<sub>0</sub> the step is half reflected and half transmitted creating two symmetrical opposite polarity voltage steps which propagate away from the load leaving between them a voltage drop across the load of V/2 - -V/2 V The voltage steps reflect from the ends of the line and return ending the voltage pulse across the load The duration of the output pulse is 2D/c where D is the length of each transmission line and c is the velocity of the pulse on the transmission line 2013-07-01 12 10 15 own Chetvorno cc-zero Uploaded with UploadWizard Transmission lines Pulse generators Blumlein generators Animated GIF Animations of electronics | ||||
