A resonant two‐string LED driver with power factor correction and passive current sharing is proposed. By controlling one output current, the other output current of the two‐string LED driver can be controlled via passive current sharing, which makes its control simple. The proposed converter uses only one active switch and one magnetic component with single‐stage power conversion, thus it benefits from low cost, small volume, light weight and high efficiency. The proposed converter is studied and experimental results of a 75 W two‐string LED driver are provided to verify the studied results. [ABSTRACT FROM AUTHOR]
