OpenAlex İngilizce

In this study, firstly, the harmonic distortions of terminal voltage and current of a three-phase 1,5 kVA, 150V, 50 Hz, and four poles permanent magnet excited Claw Pole Synchronous Generator (CPSG) supplying a 6-pulse rectifier load are simulated using its 3D Finite Element Model (FEM) in Ansys Maxwell software environment. Then, various low-pass passive filters are designed with a practical approach to reduce the terminal voltage and winding current harmonics in the analysis system. Finally, the terminal voltage and current harmonic distortions, losses, torque oscillations, and efficiency of the modelled CPSG are evaluated when the designed filter is connected to the system. According to the numerical results obtained, the best-performing filter among the designed ones is determined. It is also concluded that with the help of this best-performing filter, the terminal voltage harmonic distortion, losses, torque oscillations, and efficiency of the CPSG are considerably improved.
