This article analyzes the inefficiencies present in four wire electrical systems where linear unbalanced loads are connected. The new reference currents are proposed for the selective compensation of the inefficiencies using a three-legs shunt active power converter. The positive-, negative-and zero-sequence components of voltages and currents in load terminals determine the compensating currents that cancel the inefficient power flows. A new method for the control of the voltage unbalances in the split DC bus is proposed. Simulation and experimental results demonstrate how the proposed compensating currents improve efficiency in systems with voltage asymmetries and current unbalances.

Modeling of three-phase grid connected voltage source inverters (VSI) often involves simplifications like constant DC-link voltage or averaging over a switching period. These simplifications remove transistor switching and DC-link capacitor dynamics from the model. In this paper, a three-phase VSI with LCL filter is modeled as a state-space system using three-phase representation. DClink voltage is not considered constant and no averaging is used. The model becomes a piecewise linear system which includes dynamics from both switching and variable DC voltage. Component values in each phase are treated separately, which enables simulation of unbalanced systems. Since no transformations are used, there is a one-to-one relationship between the model and real variables. It also allows non-sinusoidal grid voltages. Simulation of dead-time and rectifier operation is described and tested. Modeling and equations are described in detail. The model is verified by simulation and experiments.

There are several ways to model three-phase grid connected voltage source inverters (VSI) with LCL filter. Such models often use simplifications like constant DC-link voltage or averaging over a switching period. These simplifications remove transistor switching and DC-link capacitor dynamics from the model. In this paper, a comprehensive modeling of a three-phase VSI, including a LCL filter is described and compared to models using one or more of the simplifications above. A comparison is also made with simulations based on Simulink SimPowerSystem toolbox. Advantages and disadvantages of different models are discussed. All simulations are verified by comparing with experimental results.
