A Modified Valley Fill Electronic Ballast Having a Current Source Resonant Inverter With Improved Line-Current Total Harmonic Distortion (THD), High Power Factor, and Low Lamp Crest Factor

IEEE Transactions on Industrial Electronics, 2008
In this paper, a modified valley fill (VF) circuit is employed to combine with a current-fed resonant inverter as a passive high power factor (PF) electronic ballast. A conventional VF circuit limits the line current to conduct when the conduction angles are: 30deg les omegat les 150deg and 210deg les omegat les 330deg during the line period, which ...

Hybrid AI Algorithms in the Design of "Wafeer" Device to Reduce Device to Reduce Total Harmonic Distortion (THD) on Low-Voltage Systems

Engineering and Applied Sciences Journal
This research aims to study and develop hybrid artificial intelligence algorithms used in the Wafeer device, which is designed to reduce capacitive harmonic distortion (THDi) in three-phase low-voltage electrical networks. The research is based on combining the mathematical approach of the Hodgkin–Huxley model with digital processing and machine ...
