Description
Technical Field

Background
Pulse power technology is moving towards higher voltages and steeper pulses, and voltage dividers are commonly used in the field of pulse power technology to measure high voltage pulse waveforms. In order to make the measured waveform accurate and reliable, the voltage divider must be calibrated by using a square wave generator. The requirements for the square wave generator are to be able to output a flat-top wave with as steep a rising edge as possible and with as high an amplitude as possible.
Referring to fig. 1, the square wave generator mainly comprises a direct current high voltage source, a pulse forming line, a switch and a pulse transmission line, wherein after the direct current high voltage source charges the pulse forming line, the switch is turned on, and a square wave signal is generated on a matched load through the pulse transmission line. The switch section inductance is a main factor influencing the rising edge of the square wave, the output of the sub-nanosecond square wave is realized, the switch section inductance is required to be very low, for example, 50-ohm load impedance is taken as an example, the rising edge is 1ns, and the discharge inductance cannot be larger than 22.7 nH. The subnanosecond square wave generator generally adopts a mercury switch, a high-pressure gas switch or a membrane switch as a discharge switch, the mercury switch can realize the leading edge less than 1ns, but the working voltage of the mercury switch is generally not more than 2 kV. The high-pressure gas switch is large in size, a low-inductance loop is difficult to achieve, sub-nanosecond output is difficult to achieve generally, the switch needs to be filled with high-pressure gas, a gas storage and inflation system needs to be configured, and therefore the high-pressure gas switch is large in size and inconvenient to use. The membrane switch has higher working voltage, but the membrane can only be used once, the membrane needs to be replaced after each discharge, the operation is very complicated, and therefore, no mature product exists at present.
