Development of scientific fundamentals of building of multi-level voltage inverters for alternative power sources in the system Smart Grid
New conception of building of industrial multi-level autonomous invertors on the base of spectral orthogonal transforms of discrete functions with m-ary argument and m-ary counting system. Means and devices to compensate reactive load power for autonomous multi-level invertors are developed. Method for building of energy-supply systems on the base of multi-level invertors and parallel filter-compensating devices is proposed. Structure of power part and control system of three-phase autonomous invertors and system for providing of assigned value of non-symmetry factor are developed.
