When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

A thesis by Manjing Xie from Virginia Polytechnic Institute and State University in partial fulfillment for her degree of Master of Science in Electrical Engineering, gives a really nice treatment of ...

Long gone are the days when only engineers that worked with large electric motors and high power electric loads need worry about power factor. The introduction of switching power supplies into ...

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 ...

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 ...

JEOLLANAM-DO PROVINCE, South Korea, Dec. 18, 2025 /PRNewswire/ -- Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer ...

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 ...
