When a sinusoidal voltage is applied to a non-linear circuit, both the resulting current and the voltage waveform become non-sinusoidal. Through Fourier series decomposition of these non-sinusoidal waves, the component with a frequency equal to the power system frequency is identified as the fundamental wave, while components with frequencies higher than the fundamental are termed harmonics. A vas...

APF and SVG are two important devices used in power systems to improve power quality. We frequently encounter them in our work; what are the differences between them, and what are their functions? 1.What is APF? The Active Power Filter (APF) is a specialized device for mitigating power harmonics, developed using modern power electronics and digital signal processing technology based on high-speed ...
