This workflow reference covers the design, analysis, and software development for a Single Ended Primary Inductor Converter, commonly known as SEPIC, which is powered by a 12 Volt lithium-ion battery and is converting voltage to 18 Volt to power 36 LEDs divided in 6 module with each 6 LEDs in series. The developed software include a simplified BMS (battery management system) to watch over the battery status, supervisory logic to coordinate mode of operation and two closed-loop controllers (SEPIC voltage and LEDs current).
