While the terms are sometimes used interchangeably, there's a key conceptual difference between Real-Time Power Factor Correction and Active Power Factor Correction. 1. Real-Time Power Factor Correction (PFC) This is a functional description. It describes any power factor correction system that can dynamically adjust its compensation in response to changes in the load. Goal:&nb...
The Problem: Variable Speed Drives Generate Harmonics What is a Variable Speed Drive (VSD/VFD)?A Variable Speed Drive (VSD), also commonly called a Variable Frequency Drive (VFD) or Adjustable Speed Drive (ASD), is an electronic device that controls the speed and torque of an AC electric motor by varying the motor's input frequency and voltage. How Do They Cause Harmonics?The internal design of a ...
When we talk about modern power systems, two technical domains often overlap but are not always fully understood together: electromagnetic compatibility (EMC) and power quality. Both play crucial roles in ensuring that electrical and electronic equipment perform reliably and efficiently. For companies and industries adopting Static Var Generators (SVGs) and Active Harmonic Filters (AHFs)...
