1. Summary Due to the advantages of simple control and low cost of uncontrolled rectifying converter, it is widely used in switching power supply, frequency converter and other equipment. However, this kind of converter will inject a large amount of harmonic current into the power grid, and increasingly become the most important harmonic source in the power grid. Most of the frequency converters o...
Harmonics: Not a Problem Unless They Become One Harmonics in modern power systems are now considered “the new normal” due to the widespread use of non-linear loads. While harmonics can lead to issues such as overheating, overloads, and resonance, they don’t always pose immediate problems. The key is understanding when harmonics are actually causing harm. When Should You Ac...
