Abstract
Nanosecond(ns) pulses have been proven to drive DBD more efficiently. However, since the DBD device is a capacitive load, which will cause distortions in the pulse waveform of the power supply. To maintain the ns pulse waveform, a parallel resistor is normally set to overcome the influence of DBD loads in the traditional methods, which will cause extra energy loss. This paper proposed a bipolar ns pulse power supply for DBD based on Blumlein transmission lines (BLTs) and pulse transformer. It does not need to set a parallel resistor and can adapt well to the load characteristics of DBD. This topology can output bipolar ns pulses on DBD loads with a rise time of 100 ns, a pulse width of 300 ns, an adjustable amplitude of 0-5 kV, and a maximum repetition frequency of 20 kHz. In this context, the operating characteristics of the circuit are derived based on the lossless transmission line model and Laplace transform, and then the correctness of the theoretical derivation is verified by the prototype. The results showed that the proposed ns power supply can drive DBD loads with adjustable output voltage amplitude and frequency.
