A single-phase hybrid active power filter with photovoltaic application

The past several years have seen a rapid increase of power electronics-based loads connected to the distribution system. These types of loads draw nonsinusoidal current from the mains, degrading the power quality by causing harmonic distortion. This thesis proposes a single-phase hybrid active power...
