It is found that the gas flow is mainly controlled by instantaneous arc power and the maximum of gas flow appears not at peak pressure, but at current zero.
结果显示,气流的改变主要受电弧瞬时功率控制,最大流量不是发生于压力峰值时刻而是出现在电流过零时。

The method of instantaneous value comparison for source current control of unity power factor rectifier possesses advantages of simplicity as well as valid restriction for maximum switching frequency.
