초록
The life of a fluorescent lamp is greatly affected by starting scenario and crest factor. This paper will propose a new crest factor control method in electronic ballast for fluorescent lamp using Pulse Frequency Modulation (PFM), which employs a passive Power Factor Correction (PFC) circuit in the input stage. The operation of parellel-loaded circuit, the switching frequency. and the characteristics of electronic ballast with the proposed PFM control scheme are described in detail, and its validity is verified by the simulation results.
