The electromagnetic modeling and the co-simulation of a direct drive axial flux permanent magnet synchronous generator

Abstract

Direct drive (gearless) axial flux permanent magnet synchronous generators (AFPMSG) are designed as multi-pole for use in vertical axis wind turbines. In particular, there are multi-pole core/coreless stator structures with axial flux for use in vertical axis wind turbines (WT) that can be designed in a compact structure at low wind speeds. In this study, the parametric simulation studies have been carried out according to rotor mechanical speeds with certain linear steps depending on different wind speed scenarios for an AFPMSG designed with 16-pole and cored stator for 5 kVA rated power with the finite element analysis (FEA) software. According to the analysis results obtained, the performance of the generator is reported and current, voltage, power losses and the flux distribution are investigated. In addition, the DC link voltage at the output of the DC-DC boost converter circuit due to wind speed changes is adaptively controlled for AFPMSG, which is co-simulated with the power electronics interface used at the generator output. Thus, both power electronics circuit performance and generator side have been simulated simultaneously with electromagnetic modeling. Therefore, the performance of the designed AFPMSG, which is modeled in three dimensions (3D) before the prototype stage, can be determined under more realistic conditions.

The analysis of three level inverter circuit with regard to current harmonic distortion by using ANFIS

“…The parameter estimation in power electronics circuits is an important step before the experimental realization of the circuit. For this purpose, the power electronics circuit interface is used in order to obtain a variation data set with certain input variables in linear steps [24]. In this study, ANFIS technique is proposed to estimate the THD value of the output current of a three-phase three-level inverter circuit.…”
