The phrase power factor frequently is used in the electrical and power electronics industry. For example, home, office, and industrial electrical equipment often is fitted with power factor-corrected ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

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 ...

Welcome to my first blog post that explores fundamental principles of electrical engineering and attempts to tease out some new insights. For many of you, this will be a refresh of concepts you ...

Linear Technology Corporation’s LT3798 is an isolated flyback controller with single stage active power factor correction (PFC). Efficiencies greater than 86% can be achieved with output power levels ...
