Elimination of higher harmonics of source currents by a use of series filters

Periodic nonsinusoidal waveforms can be filtered by filters of higher harmonics. Parallel filters of higher harmonics have got big install power |S_N|. Minimization of deformation of the input currents can be carried out by means of series filters, too. This paper shows simulations of parallel and series filters of higher harmonics of currents in full-wave rectifiers, which are done in SPice program. Install power |S_N| is smaller in series filters than in parallel ones and this is one of the most important advantages of these filters.
