인가전압 파형에 따른 표면 유전체 장벽 방전의 에너지 및 전력 소모량 특성

초록

Dielectric barrier discharge(DBD) is categorized into volumetric dielectric barrier discharge (VDBD) and surface dielectric barrier discharge(SDBD). In the field of particle charging, VDBD devices have a complex structure compared to SDBD devices, and the plasma’s generation direction hinders the flow of particles. In addition, the research on the waveform of the applied voltage is limited to relatively regular non-sinusoidal waves such as square waves and triangular waves. Therefore, in this study, the energy and power consumption characteristics of SDBD under four low-frequency applied voltage waveforms were studied. The results of the study show that Type 4 has a higher energy and power consumption than other types of applied voltage waveforms, 4.75W and 6.10W, respectively, according to the calculation method using the Lissajous curve and voltage × current, and this can be visually verified through discharge photograph.
