The approach is an alternative to d - q and alpha - beta transformation based approaches and allows to model and design the control system directly in the (the frame. Simulation results of three and four-leg inverters operating as multifunctional interfaces of distributed energy resources are presented, as well as comparative results of the proposed approach and other abc frame-based approaches to control four-leg inverters.
