Harmonic Distortion Optimize Power with Active Harmonic Filters Introduction to Non-Linear Loads and Harmonic Distortion Non-linear loads, particularly in industrial and commercial settings, are significant contributors to electrical power quality issues. A prime example of a non-linear load is the Switch-Mode Power Supply (SMPS), which is prevalent in most digital electronic equipme...
Abstract Harmonic distortion in power systems is a critical challenge that electrical engineers face, especially in today's complex and technology-driven environments. The proliferation of non-linear loads—such as variable frequency drives, power electronic converters, and uninterruptible power supplies (UPS)—has led to an increase in harmonic distortions that degrade the quality of po...
The generation and impact of harmonic problems Harmonics in electrical systems are caused by nonlinear components, which distort the sine wave of the electrical current. As power electronics become more common, voltage distortion, or harmonics, also increases. Devices like variable frequency drives (VFDs), uninterruptible power supplies (UPS), and inverters introduce different types of harmonics i...
Managing Non-Linear Load Harmonics with Active Power Filters Introduction Non-linear loads are becoming a significant challenge in today’s electrical systems. These loads cause the current to be non-sinusoidal, even when connected to a sinusoidal voltage source. This non-sinusoidal current contains harmonic currents that interact with the power distribution system, leading to v...
What is Active Load Balancer (ALB)? The Active Load Balancer (ALB) is an effective solution to solve power quality issues caused by waveform distortion, low power factor, voltage variations, voltage fluctuations, and load imbalances.

What are Even and Odd order Harmonics? Even and Odd Order Harmonics refer to the classification of harmonics in an electrical system based on their frequency in relation to the fundamental frequency. Understanding the distinction between even and odd harmonics is important for analyzing and mitigating power quality issues. 1. Harmonics Overview: Fundamental Frequency: The base frequency of th...
Benefits of reactive power compensation What is reactive power? Reactive power is the electrical energy used to establish and maintain a circuit's electric and magnetic fields, particularly in devices with electromagnetic coils. Reactive power is measured in VAR (volt-amperes reactive) or kVAR (kilovolt-ampere active). The formula for reactive power is: Q=V×I×sinϕ Q: reacti...
How to do power factor correction?Introduction to Power Factor Correction: Importance and Design The growing integration of photovoltaic (PV) systems into the grid has created challenges for utility providers. One of the primary concerns is that many power electronics used in these systems consume reactive power, leading to a low power factor and system instability. As a result, power factor corre...
