In electrical engineering, the power factor (PF) of an AC electrical power system is defined as the ratio of working power (measured in kilowatts, kW) absorbed by the load to the apparent power (measured in kilovolt amperes, kVA) flowing through the circuit. Power factor is a dimensionless ...
Power Factor Improvement Power factor improvement refers to the process of increasing the power factor of an electrical system, which is the ratio of the real power to the apparent power consumed by the system. A low power factor can result in increased energy consumption, reduced efficiency, and...
PDM control and passive filtering are combined to improve, to a significant degree and at lower costs, the power factor of an AC/AC power converter consisting of a single-phase diode bridge rectifier and a series inverter without the smoothing filter of the DC voltage. A low-pass filter abso...
Power-factor improvement and harmonic reduction in ac line current, as well as stable and reliable operation, are very significant areas in the high-power ac-dc converter. The improvements of these characteristics of the single-phase converter may be generally difficult compared with the polyphase ...

Linear induction motors have long been known to have low power factor, not merely on account of the usually large airgaps that they require, but also because a considerable proportion of the reactive VA arises as the result of the transient phenomena associated with the front and back edges of...
1) power factor improvement 功率因数提高1. The principle of voltage adjustment and power factor improvement in capacitor were analyzed,and the choossing approach was introduced. 本文分析了电容器作为无功补偿装置在电压调整和功率因数提高方面的作用原理,同时介绍了具体应用中电容器的选择方法。
