A full-digital dimming ballast with a digital power controller (DPC) for a fluorescent lamp


This paper presents a full digital ballast using a dedicated digital power controller (DPC) with a full digital control method. The proposed DPC is designed to have a variable frequency output pulse such as pulse frequency modulation (PFM) of 8 or 12-bits resolution, as well as a typical microcontroller feature including a sampled 8-bit A/D converter with… (More)
