Abstract
• The distribution of the electromagnetic force on the winding of the set is analyzed. • Simulating the electric field distribution in the electrostatic precipitator. • The power quality of the electrostatic precipitator is improved by a passive filter. • The total harmonic distortion of the transformer/ rectifier set is reduced. • Enhancing the power factor of the transformer/ rectifier set by the passive filter. Electrostatic precipitators (ESPs) are industrial emission control units. The ESPs are designed to trap and remove dust particles from the exhaust gas stream by using the force of an electric field, which is produced by a high-voltage power supply. One of the main problems of these power supplies is the presence of non-linear elements that adversely affect the power quality of the system. In this paper, a transformer/rectifier (T/R) set is modeled as a high-voltage power supply for an ESP, and the distribution of electromagnetic forces on the set is analyzed using the Finite Element Method (FEM). Additionally, the current waveform and Total Harmonic Distortion (THD) of the T/R set are modified by designing and utilizing a passive filter for the system. First, the working principle and operation of the T/R set are modeled. Then, the electromagnetic design of the T/R set is evaluated by the finite element method and the transient analysis of the flux densities, and associated radial and axial components of electromagnetic forces distribution on the T/R set. Afterward, a wire-plate ESP configuration is modeled and analyzed based on the Electric potential and Electric field. Finally, the design method of the passive filter is explained, and it is shown that the utilization of the designed passive filter has significantly reduced the THD of the T/R set.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
