Harmonic suppression device

In recent years, the rapid advancement of power electronics technology has led to the widespread adoption of semiconductor applications in a wide range of fields, from home appliances and office automation equipment to industrial machinery. This has resulted in an increase in voltage distortion in the power system due to harmonic currents generated by these devices, becoming a serious issue particularly in large cities, industrial areas, and residential neighborhoods. The occurrence of these harmonic disturbances is not limited to the premises; they can also cause failures, overheating, malfunctions, and reduced lifespan of loads in factories connected to the same distribution line, as well as flickering lights and TVs in office buildings and households, leading to significant problems. The use of power under such conditions affects the management of distribution lines by power companies, raising concerns about quality degradation. Therefore, measures that align with the management standards of power companies are required to ensure power quality.
