Constitutive Currents and Power Components for polyphase load analysis under nonsinusoidal and unbalanced conditions

The recently proposed Constitutive Currents and Power Components (C
²
PC) framework for the analysis of single-phase nonsinusoidal systems is extended further to polyphase unbalanced networks. The C
²
PC decomposition provides a time-domain refinement of the Currents' Physical Components (CPC) approach. A particularly appealing feature of the C
²
PC framework is that it does not require the load admittance.
