Low harmonic distortion of electronic ballasts / Hafizi Zakaria [PDF]

, 1998
Recent energy audit for lighting suggested the use of Electronic Ballasts instead of the conventional Magnetic Ballasts. It is more superior in term of power saving as well as more lumen per watt of input power used.

MITIGATION OF HARMONIC DISTORTION USING OPTIMUM PHASE-SHIFT MULTIPLE PARALLEL INVERTERS

Journal of Engineering and Sustainable Development, 2018
It is clear that the harmonics in power systems have many negative impacts and therefore it is inevitable to reduce their amount to the accepted level and one of the interesting approach to reduce the harmonic distortion is to synchronize phase-shifted ...
