Abstract： Plasma assisted ball milling technology requires high voltage power supply to excite the plasma field. However, high voltage plasma ball milling power supply has many problems such as large numbers of switch tubes, complicated control timing, and low reliability. Therefore, the high voltage plasma ball milling power supply based on single tube structure has been developed. Firstly, the working principle of the main circuit is introduced, and the inherent resonance frequency and resonance parameter selection of the primary resonance network are analyzed in detail. In addition, the voltage gain of the transformer and load series resonance network is utilized to further increase the amplitude of output voltage. Through Simulink software, the main circuit waveforms and the resonance voltage gain are verified. The peak-to-peak output voltage reach more than 24 kV. Based on the above, a prototype with an output power of 3 kW is developed, and the plasma field is successfully excited and used in auxiliary field ball milling.
