Abstract: This paper presents a comparative analysis of three current decomposition methods in three-phase systems without neutral wire on the basis of some case studies. The analysis takes into consideration the Currents' Physical Components (CPC) introduced by Professor Czarnecki in 1988 [1], the active and the reactive components of the p-q theory of the instantaneous power introduced by Professor Akagi and his coauthors in 1983 [2] and a modified variant of the Akagi's components proposed by the authors for the operation under unbalanced or nonsinusoidal conditions [3]. We propose four components of the current space-vector in terms of DC and AC components of the instantaneous active and reactive powers. The term of supplementary useless current vector is also pointed out. The analysis shows that the current decomposition which respects the definition of the instantaneous apparent power vector is useful for compensation reasons only if the supply voltages are sinusoidal.!
A modified definition of the components of the current is proposed for the operation under nonsinusoidal voltage conditions. This case studies based-analysis allows finding again some deficiencies that Professor Czarnecki has pointed out relating to Akagi's current decomposition [4], [5]. It is shown that the proposed active and reactive current components are identical to those of Czarnecki's CPC theory.
