Design, simulation, and experimental implementation of pmsg based wind energy conversion system

In recent years, the increased installed capacity of wind energy has enhanced its share among renewable energy sources. In addition, the development of power electronics-based power converters has accelerated the integration of wind energy conversion systems into renewable energy systems. When the number of levels of multilevel inverters increases, the output voltage harmonics decrease. Moreover, they can operate at low switching frequency and high efficiency. In this study, a five and seven-levels PUC-type multilevel inverter is proposed for PMSG-based wind energy conversion systems. This proposed PUC multilevel inverter has more advantages compared to other multilevel inverters. The designed PMSG-based variable speed wind energy conversion system consists of five main components: three-phase PMSG, three-phase diode rectifier, DC-DC boost converter, PUC multilevel inverter, and load. The proposed PUC multilevel inverter type PMSG-based variable speed wind energy conversion system is designed and simulated. In addition, the design and experimental implementation of the proposed system are carried out in a laboratory environment. In the laboratory environment, the input voltage of the PUC7 and PUC5 type multilevel inverter is determined as 45 V. In addition, the experimental setup is prepared for both five and seven-levels using two different loads. The values obtained from different loads are analyzed and the results are compared electrically.
