Hybrid 2D-3D Space Vector Modulation Voltage Control Algorithm for Three Phase Inverters

This paper presents a hybrid 2D-3D space vector modulation control algorithm for three-phase inverters where the fundamental output voltage is controlled to a balanced magnitude and phase angle regardless of the load condition-balanced or unbalanced. Different topologies including three-wire and four-wire topologies are considered in the paper. The voltage magnitude and phase angle of the inverters' fundamental output are precisely controlled, and hence, the control algorithm offers synchronization controllability over generation control in distributed generation systems. The total harmonic distortion (THD) of the inverter output is smaller when compared to other control algorithms that operate solely in 2D or 3D modes. The numerical efficiency and simplicity of the proposed algorithm are validated through conducting MATLAB/Simulink simulations and experiments for both balanced and unbalanced load conditions.
