Practical work in the elimination of harmonics involves implementing various techniques to reduce unwanted harmonic frequencies in electrical systems. Harmonics can lead to power quality issues, such as increased energy losses and equipment overheating. To mitigate these effects, passive filters and active filters are commonly used. Passive filters attenuate specific frequencies, while active filters dynamically generate reverse currents to cancel harmonics. Another approach is selective harmonic elimination (SHE), often used in multilevel inverters, which involves adjusting switching patterns to suppress specific harmonics. These methods improve power quality, enhance system efficiency, and extend the lifespan of electrical equipment.
