This paper presents the analysis, design and simulation of a digital control strategy for an electronic ballast to supply a 100 W high frequency Electrodeless Fluorescent Lamp (EFL). The electronic topology consists of a single-stage SEPIC power-factor converter associated with a half-bridge asymmetric LCC resonant inverter. In this configuration, the dimming capability based on a low-frequency burst-mode...
This paper presents the design and development of an electronic ballast for electrodeless fluorescent lamps operating at 250 kHz. In this system, a dimming control based on a low-frequency modulated PWM signal is proposed. The topology is composed of a Single-Ended Primary-Inductance Converter (SEPIC), used as power factor correction stage, integrated with a resonant half-bridge inverter, used as...
