Introduction: When "Refueling" Becomes "Charging," Power Quality Becomes the New Safety Battleground The recent spontaneous combustion of an vehicle in Shanghai during charging, with the official preliminary explanation citing "the use of substandard power by the owner," has sent shockwaves through the community. This incident not only caused panic among owners but also revealed a long-overlooked ...
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...
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...
How Does a Static Var Generator Help Stabilize Voltage? Electricity is a very important part of modern life. It powers our homes, schools, hospitals, and factories. For electricity to work safely and efficiently, the voltage must stay stable. If voltage is too high or too low, electrical equipment may not work properly or may even be damaged. In this article, we will explain what voltage is, what ...
