Abstract

In order to master the high-frequency detection performance of the VFTO external sensor

it is necessary to carry out calibration research of the sensor. The high-frequency calibration sourcesofexisting VFTO sensor mainly adopts gas switch or film switch design

which has such problems as large volume

consumption of gas or insulation film and short life and so on. In order to solve above problem

a high voltage step wave generator and circuit for calibration of VFTO external sensor are designed. Based on a MOSFET solid state switch

a high voltage step wave generating circuit is proposed. The influence of the circuit board layout of the high voltage step wave on the output step waveform and the rising time is analyzed. The transmission of the output voltage waveon the calibrated circuit is analyzed through wave process calculation. The simulation and experimental measurement research are performed. The influence factor of the output waveform of high voltage step wave generator is verified and the key parameters of the step wave generator is defined. A high-voltage step wave generator and calibration circuit with the rising time of4.8 ns and the average flat-top continuous voltageof up to 5 kV has been successfully developed to meet the calibration requirements of high-frequency response characteristics of the external transient voltage sensors.
