A much better solution is a Multi Input Single Output (MISO) control. In such a case, not only is the output voltage controlled but also the output current and the output filter inductor current. It seems that using a Passivity Based Control (PBC) is just one of the better solutions for a VSI. The paper presents simulations of a modified Improved PBC (IPBC2) using a stationary αβ frame in the event of an unbalanced load in a 3-wire delta load. The simulations were verified using the measurements of a 3-phase inverter experimental model with dynamic balanced and unbalanced loads.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.eie.24.4.21474">http://dx.doi.org/10.5755/j01.eie.24.4.21474</a></p>}, number={4}, journal={Elektronika ir Elektrotechnika}, author={Rymarski, Zbigniew and Bernacki, Krzysztof and Dyga, Lukasz}, year={2018}, month={Aug.}, pages={27-31} }
