要約(日本語): We are reporting on designs for high voltage bipolar and unipolar pulse generation used as a low cost power supply for efficient Dielectric Barrier Discharge (DBD) plasma generation. These pulses were generated by using SIDAC or Silicon Diodes for Alternating Current which is a bidirectional high voltage switching device and is designed for direct interface with the power line. When applied voltage (VSIDAC) meets or exceeds its breakover voltage (VBO), the SIDAC will switch from blocking state to conducting state. If the number of SIDACs in series connection is N, the breakover voltage of this connection will be increased to N times. Then, a low cost high voltage pulse with tens of kilovolt derivation is created without controlling by switching characteristic of these SIDACs. In our work, we used a series connection of ten SIDACs (K1V38(W)) connected to a step-up transformer and a conventional AC power supply in order to generate high voltage bipolar pulses. However, if this connection of SIDACs were connected to a capacitor bank and a DC high voltage power supply, then the high voltage unipolar pulses were generated. The experiments demonstrated that such proposed configurations is capable of generating the less expensive high voltage pulses which have been successfully applied for inexpensive and efficient DBD plasma generation.
