Research for High-Voltage Nanosecond Rectangular Pulse Generator

Abstract:

In order to calibrate the response characteristic of voltage dividers, the article presents a potable high-voltage nanosecond rectangular pulse generator based on the transmission-line theory. The generator consists of DC high-voltage source, pulse forming line (PFL), special high-voltage switch, pulse transmission line (PTL), resistive load and coaxial voltage divider. The compact charging and discharging circuit is developed coaxially and the interference proof performance is excellent. The voltage amplitude and the pulse width can vary from the output of the DC high-voltage source and the length of PFL respectively. In the article the theory of pulse forming process, the design and the key devices of the generator are investigated theoretically and experimentally. The experimental results demonstrate that the generator can meet the measurement demands and export well-defined rectangular pulses with the rise time less than 751.738ps and the voltage amplitude up to 2kV.
