Aiming at the application demand of bipolar pulse voltage DBD discharge, an all-solid-state bipolar nanosecond pulse forming topology based on linear transformer driver (LTD) is proposed. The control circuit of each switch does not require additional high voltage isolated power supply in the operating state. In theory, it can achieve unlimited stacking of modules like the traditional unipolar LTD to obtain higher voltage bipolar pulse output. Each module integrates same number of energy storage capacitors with opposite voltage polarity, which makes the magnetic core's exciting current alternate between positive and negative directions under different pulse polarity, thus effectively improves the utilization rate of the magnetic core, and does not need an additional magnetic flux reset circuit. Finally, a modular compact bipolar LTD principle verification prototype was developed. The key parameters of the prototype are as follows: amplitude 0 to ±2 kV, pulse width of top flat 50 ns-200 ns, burst repetition frequency 500 kHz. All the pulse parameters can be flexibly adjusted through the host computer.
