Artificial Neural Network Controller for Reducing the Total Harmonic Distortion (THD) in HVDC
International Journal of Advanced Engineering, Management and Science, 2018 A neural network based space vector modulation (SVM) of voltage source inverter is proposed. The voltage source converter (VSC) is highly used in high voltage direct current (HVDC) transmission so that a detailed analysis and transmission of this system is carried out. In addition, a non-linear neural network controller is proposed to control the space
