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 ...

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 ...

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

Your utility Power Factor is the ratio of the system’s Real Power and the Apparent Power (Eq. 1, Fig. 1). This unitless factor ranges from −1 to 1. The Power Factor ratio aptly describes the type of ...

As a solid state light source, light-emitting diodes (LEDs) have been widely used due to their superior longevity, excellent efficacy, and friendly environmental attributes. Today, LEDs are replacing ...

There’s an increasing need for high-efficiency power conversion for a wide range of applications. Among the several available power factor correction (PFC) solutions, the critical conduction mode (CrM ...

The power factor measurement has long been accepted as an invaluable tool for identifying insulation defects, such as ageing, deterioration, moisture ingress and localized failures, involving the ...

Current regulations IEC-1000-3-2 impose strict requirements on the harmonic current content, which can be sent back to utility lines for all consumer electronic devices consuming more than 75W of ...
