Resistive Divider with Mid-Electrode for Nanosecond High-Voltage Pulse Measurement

Abstract:

Resistive dividers have been widely applied in the field of high voltage pulse measurement because of its simple structure, fast response, large power and low distortion rate [1], but measurement inaccuracy is usually coming when the rise time of pulses is less than 10ns. In the article the effects on the response characteristic are investigated theoretically and experimentally and it puts forward a solution that a mid-electrode is joined to transform the distributed capacitance into the one from high voltage side to mid-electrode and the one from mid-electrode to earth in series connection. A new resistive divider with mid-electrode is designed with high voltage side of 10.2kΩ, low voltage side of 10.01Ω and ratio of 1061.86. It is revealed that the divider has excellent response characteristic with the step response time of less than 1.6ns and the measurement uncertainty of less than 1%.
