There's always a besserwisser in the crowd and after receiving a couple of anonymous emails from one claiming to be an IEEE engineer, I brought together again, a collection of forces to help me better ...

Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...

Why is Power Factor important? The phase relationship between the ac-power-line voltage and current is related by a term called power factor. For a purely resistive load on the power line, voltage and ...

Researchers develop a sensorless boost PFC method delivering near 0.9998 power factor and low distortion, enabling smaller and more reliable power supplies for consumer electronics. Single-phase power ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...

Electronic ballasts for fluorescent lighting deliver high efficiency and long lamp lifetimes. A new and simplified control circuit demonstrates complete control of the ballast, including all necessary ...
