TLDR
In this article, an ac voltage-regulation method based on the principle of both forced ignition and extinction of thyristors acting as switches was described. This method was found more efficient than the conventional one, assuring a higher power factor for inductive loads.Abstract:

Fluorescent light dimming
TL;DR: In this article, a dimmer for a fluorescent light in which the fluorescent light is supplied with an electrical signal having a varying magnitude, the dimmer positioning a notch of reduced signal magnitude within the electrical signal for controlling the illumination level of the light, wherein the intensity level is dependent upon the position of the notch within the varying electrical signal.

Dynamic analysis and controller design for a center-point-clamped ac-ac converter
TL;DR: In this paper, a novel topology based on center-point-clamped circuit configuration for ac-ac power conversion has been presented, which introduces a unique methodology to clamp the voltage to the midpoint of the input transformer thus reducing voltage blocking requirements on the bi-directional switches employed in such direct ac-AC converter.
