Resonant Circuit Design Procedure for Multi-watt T5 Electronic Ballasts

Abstract

This paper proposes a resonant circuit design procedure for multi- Watt magnetically-controlled electronic ballasts. The procedure is focused on the ballast performance, which has the advantage of operating at constant-frequency, and complies with current IEC standards (IEC 60081) regarding nominal lamp operation, namely electrode safe operation. Data collected from T5 tubular fluorescents lamps manufacturers and the Sum of Squares (SoS) technique are both used to define the suitable design methodology for the power range of the selected T5 lamps. Experimental results for a set of T5 fluorescent lamps are presented in order to validate the entire design procedure.
