Single Stage Ballast for Hps Lamps
In this paper will be reported the study and implementation of a single stage High Power Factor (HPF) electronic ballast for High Pressure Sodium (HPS) lamps using a LCC filter. In the recent years many authors are working to obtain single stage HPF electronic ballast for fluorescent lamps [1][2]. Normally to obtain HPF in electronic ballast for high pressure sodium lamps a Power Factor Preregu...
متن کاملHigh Frequency Electronic Ballast Provides Line Frequency Lamp Current
Most electronic ballasts for fluorescent lamps provide a sinusoidal lamp current at the switching frequency. The high-frequency current flowing through the lamp can generate significant radiated noise, which is unacceptable in noise-sensitive applications, such as fluorescent lights in airplanes. Using shielded enclosures for the lamps may solve the problem, but it is expensive. A discontinuous...

Electrical feedback control for driving mercury-free flat fluorescent lamp
Joung-Hu Park Jong-Bok Baek Bo-Hyung Cho Abstract — Recently, a mercury-free flat fluorescent lamp has been developed for LCD backlight application, utilizing a glow-discharge mode instead of a discharge contraction. This paper proposes a lamp-driving system with a feedback loop which prevents discharge contraction and stabilizes the operation of the lamp ignition and radiation. By measuring th...
متن کاملAdvanced Design of a Low-Cost Electronic Ballast with PFC for HPS Lamps
In this paper, an advanced design of a low-cost electronic ballast with PFC for HPS lamps is presented. The inverter stage is based on LCC parallel-series inverter with resonant current mode control. This control method avoids the inverter handling any reactive energy, minimizing both switching and conduction losses. Also, the design performs a natural power control without exceeding the maximu...
