Problems solved by technology

For example, the all-solid-state Marx and LTD circuits can flexibly output pulse square waves with adjustable pulse width and frequency, but the polarities are all unipolar pulses [23]; the pulse source using multi-level MMC can output ladder-shaped Pulse, which makes the rising and falling edges of the pulse adjustable, and can also realize bipolar pulse output. The input voltage is equal to the output voltage, and there is no voltage superposition, which is not conducive to generating high-voltage pulses; the combination of Marx and bridge circuits It is also possible to output bipolar pulses, but the number of switches is large, which increases the cost of the pulse source
In addition, the all-solid-state pulse source also has various types of topologies such as switch series and pulse transformer, which have certain advantages in some application fields, but there are also some disadvantages. For example, pulse transformers are easily affected by winding stray inductance, resulting in waveform Shock, etc.
