摘要： A switching element operates to be turned on or off at a frequency in the order of megahertz. A reactor supplies a resonance current generated by resonance of the reactor with a floating capacitance between electrodes to between the electrodes. The resonance current does not flow in a direct-current power supply. By turning a capacitor and a floating inductance into a serial resonant state, the reactor ideally supplies the resonance current to between the electrodes without influence of the floating inductance. A high-frequency voltage asymmetric in positive and negative polarities is applied to between the electrodes and a current pulse can be made into a short pulse. Therefore, finish machining with high surface roughness can be performed.
摘要翻译：开关元件工作在频率为兆赫兹的频率下导通或截止。电抗器通过电抗器的谐振产生的谐振电流与电极之间的电极之间的浮动电容提供。谐振电流不会流入直流电源。通过将电容器和浮动电感转化为串联谐振状态，反应器理想地将谐振电流提供给电极之间，而不受浮动电感的影响。在电极之间施加正极性和负极性不对称的高频电压，并且可以将电流脉冲制成短脉冲。因此，可以进行表面粗糙度高的精加工。

摘要： A silent discharge plasma apparatus includes a dielectric member, a pair of electrodes opposed to each other across the dielectric member and an alternating-current source applying an alternating-current voltage between the electrodes and causing a discharge. A gas is supplied to a discharge space, where discharge occurs, and a plasma is produced. At least one of the electrodes includes a conductive power feeding thin film on the dielectric member. When the dielectric member is destroyed and an arc discharge develops between the electrodes, the power feeding thin film is eliminated or oxidized, and the arc discharge is stopped.
