Description
Summary:Dielectric barrier discharge (DBD) can produce a large amount of active particles and has many applications in the industry. In order to study the effect of different rising edges, falling edges, and waveform voltages on DBD, a novel all-solid-state bipolar multilevel high-voltage pulse generator is proposed. Compared with other topologies, the proposed system can achieve more levels of waveforms with fewer switches. This article introduces the structure and working principle of the system in detail. Through PSPICE simulation, it is found that the capacitance of the switch junction will generate prepulse for the output. To solve this problem, an improved control strategy is proposed. Finally, a nine-level test prototype is built, which can work steadily under different loads. Meanwhile, different types of output waveforms are allowed to be generated when the control is adjusted. Finally, the main circuit uses 20 power switches and nine energy storage capacitors and this system can achieve a maximum output voltage of ±4 kV, adjustable frequency, and a total of 19 level voltage output (including 0 level).
