In this chapter, the basic principles for parallel power electronics filters are discussed. In Sect. 2.1, the influences of reactive power, harmonics and unbalance are given, which affect and degrade the practical power network. The basic circuit configuration for injecting and absorbing compensating current is discussed. Furthermore, several parallel power filters are given and compared. In Sect. 2.2, instantaneous power theories which are important for detecting the compensation current components and controlling the fast response of power electronic compensators are introduced and addressed. Finally, different power electronic converters are discussed and compared in Sect. 2.3. The effect of dc voltage variation on the switching functions are also introduced in Sect. 2.3.
