Summary
The power converters are becoming to typical load in the distribution mains. Input circuits of this converters are often designed as a line-commutated rectifier, which consists of power semiconductor devices. The converter is non-linear load in the mains and its current consumption it is not only sinusoidal, but there are higher current harmonics, which unfortunately influence feed system. For the reduction of the higher harmonics influence the filters compounded by inductors and capacitors are used. However these devices have many basic disadvantages, for example they and inner line impedance are making resonance circuit with sharp tuned resonances. All these undesirable properties it is possible to remove by using active power filters. The principl of the filter is such, that a filter current is injected to mains by generation of output voltage out of converter. That converter is able to add or to take the theoretically any course of current in mains.
