Özet:

This paper presents ANN based control of single stage nineteen-level modular inverter topology integrated to grid. The inverter operation, filter design and integrated control of single stage power conversion for maximum power extraction and unity power factor current injection to grid are presented. The simulation study of the topology and control is carried out in MATLAB/SIMULINK and an experimental setup for 2.5 kW is developed. Effectiveness of the designed filter is verified in terms of load current harmonic profile. The economic advantage of the topology is validated through comparison in terms of inverter and filter component sizing with similar switch count neutral point clamped inverter. The effectiveness of the control algorithm is validated for steady and transient conditions.<
