This paper presents a dimmable electronic ballast for T5 fluorescent lamp. A modified dimming method is proposed based on variable DC bus and dedicated IR21592 IC. A combined method of dc link voltage control of resonant inverter, and a fixed phase angle of resonant inverter that is kept constant using the phase-locked loop (PLL) is employed. The electrodes heating is evaluated in order to guarantying the correct lifetime of T5 fluorescent lamp using Sum of Squares (SoS) method. Simulation, mathematical analysis, and experimental results with IR21592 IC were demonstrated for different operation conditions.

“…The full-bridge inverter connected to a parallel-loaded resonant tank is the most common topology used as high-frequency inverter for electronic ballast. Usually there are four different resonant tanks [4] and the LC topology as shown in Fig.2 is considered in this paper. This circuit comprises a saturating and hysteretic inductor in series with a capacitor and fluorescent lamp, driven by a square wave voltage which is the output part of the inverter as shown in Fig.…”

Applying Jiles-Atherton (JA) model to investigate the nonlinear inductance performance in the electronic ballast is a challenge but very attractive issue since it is possible to carry out continuous simulation with only several input parameters. In this paper J-A model has been successfully applied to model the dynamics of resonant inverter for driving a non-linear load: a fluorescent lamp. A semi-theoretical fluorescent lamp model developed from HID lamp model is adopted in this modeling. The whole system has been implemented in the Simulink of Matlab and the simulation results of voltage across the lamp and inductor and current through them are close to those measured ones reported in the literature papers.I.

“…Basically, there are two ways to adjust the lighting levels: continuous dimming and discrete dimming. Con tinuous dimming ballast permits the light output of the lamps to be continuously controlled over a range of approximately 1%-100% of the full light output [9]- [11]. As an alternative to the continuous dimming, the discrete dimming method provides the discrete reduction in the lighting output.…”
