High Voltage Pulse Generator by Connecting Normal Coaxial Cables in Series and in Parallel without Using Blumlein Method
Authors: ,
Abstract: In order to carry out the simulation of the electrical noise, a pulse generator with fast rise time is needed. For this reason, the pulse generator using a coaxial cable is usually used. The pulse generator consists of a DC power supply, a charging resistor, a coaxial cable, a relay, and a terminator. Even the same voltage as charge voltage was outputted when the termination of the impedance was high, only the output of the half of charge voltage is obtained when the termination impedance was set at 50 ohm which is the characteristic impedance of the coaxial cable. For this reason, we have been developing a pulse generator with the same voltage as charge voltage while termination impedance was set at 50 ohm, by connecting four coaxial cables in series and in parallel.
