Abstract
- This paper presents a model of power light emitting diodes (LEDs) based on electrical variables and considering the concept of LED 'equivalent resistance', which has previously been used in discharge lamp modelling and is suitable to achieve fast simulations of LED converter systems. The model can be obtained with only some simple electrical measurements, thus making its implementation quite straightforward. The proposed model is oriented to the electronic engineering area, and it has special application for the simulation of the electrical behaviour of LEDs and dc-dc converter systems by using software like Simulink. In addition, the proposed model can also be employed for the theoretical analysis and design of LED drivers. Experimental and simulation results are obtained proving the feasibility of the proposed model. Copyright © 2017 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
