Development of the Step Pulse Generator for Calibrating the Very Fast Transient Voltage Measuring System

To calibrate non-contact sensors with fast response and high scale factor, it is critical to develop step pulse generators capable of generating standard high voltage step pulses and accurately measuring the generated waveform. In this paper, two types of step pulse generators are designed with output voltages of 2 kV and 100 kV. The 2 kV step pulse generator can generate a step pulse with a rise time of similar to 300 ps and an adjustable pulse width. A step pulse with a rise time less than 5 ns and a pulse width over 1 mu s can be generated with the 100 kV step pulse generator. The uncertainty of 2 kV step pulse generator is then analyzed by simulations and experiments. Finally, a performance comparison with step pulse generators in previous studies is carried out. Bandwidth, linearity and repeatability of the sensors can be verified with the designed two step pulse generators.

Automated summary

This paper presents the design and analysis of two step pulse generators with different output voltages for calibrating the performance of non-contact sensors. The experimental results show that the designed step pulse generators have fast response time and high precision pulse width adjustment.
