There have been concerns raised on load non-linearity as more and types are being introduced into the radar power supply system. The non-linear produces harmonic current while it seriously threatens normal safe operation environment of other system equipment. It can be difficult to design shunt active filter (APF) eliminate effect achieving stability reliability. This paper designs a hybrid opt...

This paper deals with three methods of determination of reference current for control of single-phase active filters. All this methods are based on the idea that an ordinary single-phase (system) quantity can be complemented by a fictitious second phase so that both of them will create an orthogonal and orthonormal system.
