Power quality enhancement using active power filter five-level cascade H-bridge under unbalanced and distorted grid

Electrical engineering & Electromechanics, 2023
Introduction. To improve the power quality of a supply system, the total harmonic distortion (THD) is the most important parameter in the quantification of harmonics caused by nonlinear loads. In practice, it must be less than 5 %.
