峰值堵转控制功率 [电子] peak control power at locked-rotor
提出了一种基于临界电流模式的峰值电流控制技术来实现开关电源的功率因数校正任务。
A critical current mode based on the peak current control technology to achieve switching power supply power factor correction task is proposed.
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。
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.
无功补偿可以提高功率因数，变压器的经济运行可以最大限度地降低变压器的电能损耗，需量控制能够降低企业最大峰值负荷，降低生产成本。
It concludes that reactive compensation can increase power factor. Economical transformer operation can decrease energy loss. Power demand control can shed maximum peak load and lower productive cost.
