Research on Neutral Point Drifting Technology Based on the Same Harmonic Distribution of Line Voltage

Kongzhi Yu Xinxi Jishu, 2011
Neutral point drifting technology based on the same harmonic distribution of line voltage is proposed. With the optimization of carrier phase-shifted angle and frequency modulation ratio, the harmonic distribution of three line voltages can be consistent.

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.
