TY - JOUR T1 - Comparison of T-Type Converter and NPC for the Wind Turbine Based on Doubly-Fed Induction Generator AU - Gencer, Altan PY - 2021 DA - April DO - 10.17694/bajece.826624 JF - Balkan Journal of Electrical and Computer Engineering PB - MUSA YILMAZ WT - DergiPark SN - 2147-284X SP - 123 EP - 128 VL - 9 IS - 2 LA - en AB - A three-phase T-type converter topology proposes for wind turbine based on doubly fed induction generator (DFIG). The proposed converter consists of only twelve power switches without flying capacitors or any clamping diodes. The proposed system is implemented to grid side converter of wind turbine. Fuzzy logic controllers are more widely used in wind turbines compared to traditional control systems. Fuzzy logic PI controller has been applied to T-type and the conventional neutral-point clamped (NPC) converters control circuits. Total harmonic distortion (THD) value of current of presented system is measured as 1.76%. Also, DC-link voltage utilization can be maintained. Comparisons are conducted with T- type converter and a 3L-NPC) method under same operation conditions. The proposed scheme has been carried out to verify in simulation results.
