According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

The design of a switching power supply has always been considered a blend of magic and art by every engineer that designs one for the first time. Fortunately, today the market offers different tools ...

1. Power-factor triangle relates the real power, the reactive power, and the apparent power. (Courtesy of Vector Group) Let’s start by talking about the concept of power factor (PF). Assuming ...

Independent of their individual topology and application, due to AC components in their lines switching controllers create conducted EMC interferences. Würth Elektronik MagI³C power modules are ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs. The ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...
