Methods and apparatus to improve power factor are disclosed. An example method includes detecting power provided to a power factor corrector; detecting power provided by the power factor corrector; and disabling the power factor corrector from correcting a power factor of a load for at least one ...
The “ideal” power factor is one (also referred to as “unity”). This is when there is no reactive power through the circuit, and hence apparent power (kVA) is equal to real power (kW). A load with a power factor of 1 is the most efficient loading of the supply. That said this...
Resistive loads have a unity power factor. (a) (b) Figure 1. (a)-the power factor expresses as cosθ leading power factor. (b)-lagging power factor. Image used courtesy of Ahmad Ezzeddine Power Factor Correction Power factor correction drives power factor to unity. The importance behind ...
Crest factor reduction algorithms described herein may be used to improve power amplifier efficiency during low signal power conditions compared to traditional static threshold techniques. Techniques described herein insure that the signal power level at the output of the crest fact reduction block is hel...
in this paper we propose two methods to improve the accuracy of the GS methodology. One method (B Model) reformulate the conventional genomic regression model (R model) as a binary classification problem, that offer the advantage that will increase significantly the sensitivity to detect the best...

To improve power, we modify the global test mentioned earlier to a Dunnet-based test48,49,50 as described below: (1) The test statistic \(W=\mathop{\max }\limits_{k\in \{1,\,\ldots ,\,g\}}| {W}_{k}|\), (2) Generate \({W}_{k}^{\;(b)} \approx N(0,1),k=1,...
To improve the power factor of AC side, power factor correction (PFC) converters are generally used, which actively adjusts input current waveform to sinusoidal waveform. The PFC converters are an important area of study and research in power electronics, used in practical power supplies to ...
