This paper presents new design considerations and a control strategy for a two-stage ballast
system; power factor correction (PFC) and resonant inverter (RI), for high intensity discharge …

This paper introduces a dimmable electronic ballast for HPS lamps which uses a new
strategy to implement the variation of the lamp's power, based on the variation of the …

In this paper, a new control method for electronic ballasts based on the use of a variable
inductor is presented. The main goal is to perform the complete control of the electronic …

This paper proposes a novel difference-integral controller (DIC) to improve the dimming
performance of variable-frequency single-stage electronic ballast for cold cathode …

This paper presents a constant power controller for use in the DC-AC inverter of an
electronic ballast for high-intensity-discharging (HID) lamps. The proposed DC-AC inversing …

With the global concerns on the issue of how to conserve the limited energy resources,
compact fluorescent lamps (CFLs) have been forced in a lot of countries to replace the …

In this paper, a novel variable frequency controller is proposed for a passive high power
factor electronic ballast with dimming capability and low crest factor. The ballast circuit is the …

In this paper, a digitally controlled electronic ballast is presented. The ballast corresponds to
the so-called universal or multiwatt ballasts, which are intended to operate different lamps …

In this paper, electronic ballast using resonant inverter for HID lamp is designed and
implemented. The proposed electronic ballast is used the soft switching technology ZVS …

Discharge lamps present a negative dynamic characteristic that makes necessary to use a
current limiting element. In high-frequency resonant ballasts, current limitation is performed …
