Moving from a conventional silicon-based Active Harmonic Filter to one using Silicon Carbide (SiC) MOSFETs represents a major technological leap, and the cooling system is directly impacted. Here’s a detailed look at the cooling system of a SiC Active Harmonic Filter, highlighting how it differs from traditional IGBT-based AHFs. The Core Advantage: Why SiC Changes the Game Silicon ...
The choice between installing an Active Harmonic Filter (AHF) on the power side (at the Point of Common Coupling - PCC) versus the load side (at the source of harmonics) is a critical design decision with significant technical and financial implications. Here is a detailed analysis comparing both installation strategies. Executive Summary Load-Side Installation (Local Compensation): Targets s...
Power Quality Survey: A Comprehensive Practical Guide fromPlanning to Implementation The stable operation of power systems is the core guarantee for industrial production, commercial operations, and even daily life. However, power quality issues such as voltage sags, harmonic pollution, and grounding abnormalities often lead to equipment failures, reduced production efficiency, and even safet...
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 Problems? Two Tools That Fix Them for Good Does your facility have any of these issues?---- Energy bills that are too high. Machines that run hotter than they should. Production lines that stop unexpectedly. Often, the problem isn't your equipment. The problem is the quality of the electricity that powers them. It's like giving an athlete dirty water to drink—performance w...
Stop Blaming Your Equipment: Power Quality Solutions Explained Ever had your production line halt unexpectedly? Do your facility lights dim when a large motor starts? Have you faced unexplained equipment failures or rising energy bills? Before you replace the machine or blame the hardware, consider this: the issue might not be the device itself. The issue is likely the quality of the electr...
