Abstract
In this article, the construction of a high-frequency, high-voltage commercial flyback transformer to supply an input voltage for a tesla transformer is proposed. The purpose of a demonstration is a breakdown through the air gap of electrode. To confirm the proposed method, the design of control of a flyback converter by using a commercial flyback transformer is rated with a 10 to 15 kV output voltage to supply a tesla transformer at a rated 30 kV and 120 kHz. The experimental results of an output breakdown, design of the electrode, and the setting for a 1 cm space are constructed. The electrodes consisted of the following: sphere–sphere electrode, plane–plane electrode, sphere–plane electrode, and rod–plane electrode. It was found that there was a breakdown at the output electrode in all cases. Accordingly, there was a breakdown with a 2 cm sphere diameter with reference to the IEC 60052-2002 standard; after that, it was compared with the standard table, and the atmospheric and temperature at the laboratory were adjusted, resulting to a high voltage equal to 31.5 kV.
