N2 - This paper presents the optimal light-emitting-diode (LED) array combination for the single-loop continuous-conduction mode (CCM) boost driver. The Taylor series for describing the characteristics of the LED is used to characterize the relationship between the forward voltage and current of LEDs. Moreover, in order to predict the system performance, including system stability and maximum-efficiency power conversion, the equivalent circuit models of the LED boost drivers are constructed to derive the system transfer functions. Finally, the optimal combination of a 120-pcs LED array driven by the employed single-loop CCM boost converter is obtained and verified.
