Abstract :
This paper proposes a reference current control method that controls the neutral-line current and the rotating phase currents separately and makes the system currents sinusoidal and balanced in any circuit conditions such as unbalanced or distorted voltages and/or unbalanced or nonlinear loads. Simulation results show the superiority of the power compensation theory both in definition and compensation
