Abstract :
Design and development of a rectangular current pulse generator is presented. The generator produces 15 ms wide, 100 A amplitude unipolar pulses into an 8 Omega load. Pulses with duration of 10-20 ms are essential for the development of compacts of the nanomaterial samples while avoiding grain growth on the samples dominant at long pulses. The pulses are produced by discharging the charged artificial transmission line into the load impedance equal to the surge impedance of the transmission line. These pulses obtained are applied for sintering of samples like aluminum and graphite.
