Review on DC-DC SIMO Converters with Parallel Configuration for LED Lighting Control

This work presents a review on DC-DC converters using the single-input multiple-output (SIMO) technique in parallel configuration for LED lighting control. The review focuses on the application of the SIMO methodology combined with the time multiplexing (TM) control when the converters are working in discontinuous conduction mode (DCM). In this work an evaluative comparison of the revised techniques is also carried out for DC-DC SIMO converters with parallel configuration. Additionally, a proposal is presented about the possibilities of applying the magnetic control (MC) methodology using a variable inductor (VI) in a buck converter, in combination with SIMO for the control of DC-DC converters to achieve the regulation of the output current in LED lighting driving applications.
