Self-Tuning High-Voltage and High-Frequency Sinusoidal Power Supply for Dielectric Barrier Discharge Plasma Generation

In this paper a high-voltage sinusoidal power supply controlled by Arduino DUE micro-controller is described. This generator can feed a dielectric barrier discharge (DBD) load with sinusoidal voltages up to 20 kV peak and frequencies in the range 10–60 kHz, with a maximum output power of 200 W. Output voltage can be produced either in a continuous mode, or with on/off modulation cycles, according to treatment/application requirements. This power source is equipped with on-board diagnostics used to measure the output voltage and the charge delivered to the load. With a sample frequency of 500 kHz, Arduino DUE allows to evaluate both the high voltage and the average power feeding the discharge without the use of an expensive external measurement setup. Lissajous techniques are utilized to calculate discharge average power in a quasi-real-time manner. When a load is connected to high-voltage terminals, a self-tuning procedure is carried out to obtain the best working frequency. This parameter allows to minimize power-electronic component stress and to maximize generator efficiency.

Cold Plasmas

At low pressure, cold plasmas are used for a wide range of applications such as coating, flow control, or microelectronics. Currently, this industry requires expensive vacuum systems which consume energy and time, and therefore it is very appealing to develop similar processes at atmospheric pressure. Under this condition, dielectric barrier discharge (DBD) is one of the best ways to obtain a cold plasma. The dielectric barriers naturally limit the current, and then the plasma temperature. Unfortunately, at atmospheric pressure the discharge ignition between the electrodes requires high voltage, which is generally obtained through a step-up transformer. The parasitic elements of this device exclude a smart control for the discharge. In order to overcome this default, we analyze the performance of a transformerless power supply developed with a recently released single-chip high-voltage semiconductor. The circuit uses only two high-voltage switches synthesized by means of the 10 kV SiC MOSFET (Metal Oxide Semiconductor Field Effect Transistor). The design and implementation of the electric converter are presented and validated with experiments carried out on UV excimer DBD lamps. Then, the performances of the 10 kV SiC switches are analyzed and the relevance of this device for DBD applications is discussed.

Discharge Method

The utilization of ozone is commonly applied in various fields, for instance, it is used as a disinfectant for water treatment, disinfecting, sterilizing medical devices and preserving foodstuffs. Ozone is a nearly colorless gas with a characteristic odor that can be detected by humans up to 0.01 ppm. It can be produced by the dielectric barrier discharge method,which is generally used as a method of generating ozone supplied by high voltage or also called high voltage plasma generators. High voltage plasma occurs in the dielectric barrier discharge air gap, as a result of the air failed in maintaining its insulator properties. The power supply used in this study is a parallel resonant pushpull inverter using a flyback transformer. Furthermore, this study did not use an additional magnetic loudspeaker and used ceramic dielectrics instead. 5 types of ceramics and 2 different types of granite and combined the range of air gap were used during examination and research. The research indicates that the best plasma was found in ceramics 3, 5, granite 1 and 2 with an air gap of 2mm. The current discharge in ceramic 1 with an air gap of 2 mm was higher than the others. The highest voltage discharge was on granite 2 with an air gap of 2 mm. Ceramics 3, 5, granite 1 and 2 with an air gap of 2mm had better ozone concentrations than ceramics 1, 2 and 4.
