Minimization of Voltage Harmonic Distortion of Synchronous Generators under Non-Linear Loading via Modulated Field Current

open access: yesEnergies, 2023
The synchronous generators (SGs) supplying non-linear loads have harmonically distorted terminal voltages. Hence, these distorted terminal voltages adversely affect the performance parameters of the supplied loads such as the power factor, current ...

Experimental Verifications and Simulations of Magnetic Motor of Circular Miniature Loudspeaker for Total Harmonic Distortion Improvement [PDF]

open access: yes, 2011
The reduction in total harmonic distortion of miniature loudspeaker is reported by investigating the force factor (Bl(x)). Micro tensile testing is employed to get Bl(x) vs x curves, which verify finite element simulation. Furthermore, magnetic system of
