TY - JOUR ID - TI - MODELING AND ANALYSIS OF A FOUR-LEG INVERTER USING SPACE VECTOR PULSE WIDTH MODULATION AU - Isam Mahmood Abdulbaqi AU - Ali Husain Ahmed AU - Riyadh Ghanim Omar AU - Abdullah Sahib Abdulsada PY - 2019 VL - 23 IS - 2 SP - 100 EP - 119 JO - Journal of Engineering and Sustainable Development (JEASD) مجلة الهندسة والتنمية المستدامة SN - 25200917 25200925 AB - The bad effect of zero sequence current in unbalanced load when connected to three-leg inverter, is the main challenge leading to add fourth leg and using three dimensional space vector pulse width modulation (3-D) SVPWM technique to handle this problem. The paper presents an analysis and study of this technique, depending on the average large signal model. This technique simulated by using Matlab/Simulink and the results shows good performance with low THD for different operating conditions.
