HARMONIC REDUCTION IN POWER SYSTEM Ankit Vashi B.E. ...

• Due to the presence of harmonics in both current and voltage, active filter may
not be able to resolve the issue in certain typical applications.
For the conditions where both voltage and current are leading to a deterioration in
power system, more complex filters are used which are made up of combination of active
and passive filters. Such filters are called as Hybrid Filters. [3]
Figure 8 and 9 shows single phase active filters in shunt and series configuration
respectively.
