The pursuit of perfect power quality is undergoing a fundamental shift, driven by a new semiconductor material: Silicon Carbide (SiC) . Comparing a traditional Active Harmonic Filter (AHF) with a SiC-based model reveals more than incremental upgrades; it showcases a leap in performance, efficiency, and capability. For decades, traditional AHFs have relied on silicon-based IGBTs. These components w...
The Role of Energy Storage Systems in Off-Grid Power Systems As the need for reliable and sustainable electricity increases worldwide, off-grid power systems are becoming vital. They are important for remote areas, islands, industrial sites, and places with limited access to the grid. Off-grid systems let communities and businesses work without support from national grids. This reduces the ne...
Modern power systems face a hidden threat: resonance. This occurs when harmonic currents from non-linear loads (like VFDs and rectifiers) match the electrical system's natural frequency. The result? Dangerous amplification of harmonic voltages and currents, leading to capacitor failures, overheating, and equipment damage. Traditional passive filters can ironically cause this problem by introducing...
Power Quality Evaluation: The Cornerstone of Stable Solar PV System Operation As solar photovoltaic (PV) systems gain widespread adoption in commercial and industrial settings, interest in financial returns and performance expectations has intensified. However, a critical yet often overlooked aspect throughout the entire lifecycle of solar projects—from planning and installation to oper...
