  • Abstract
    In this paper, a fully-digitalized current sharing strategy without any analog-to-digital converter (ADC) is presented and applied to light-emitting diode (LED) lighting. By doing so, the cost for digital control is reduced significantly. Above all, the proposed current sharing method has the capability of resisting variations in input voltage and component parameter. And this is verified by experiments and very suitable for LED street lighting.
