There is some level of confusion upon goals of compensation in systems with nonsinusoidal voltages and currents (NV&C), especially considering that compensation with switched compensators is a recursive process. This recursive nature of compensation is often ignored in discussions on compensation. This paper presents results of studies on recursive compensation with a switching compensator, aimed at reducing the supply current to its active component, defined according to Fryze, according to CPC power Theory, and to its working component. The paper also shows that the instantaneous reactive power p-q theory-based algorithm for switching compensator control, does not provide, in the presence of the supply voltage harmonics and/or asymmetry, right control of such compensators. © 2010 IEEE.
