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).
Prerequisites and related content:
This content has been presented in a webinar, you can take a look for further explanations:
https://ch.mathworks.com/videos/series/how-to-develop-dc-dc-converter-control-in-simulink.html
It is strongly reccomended to complete following free Onramps before taking a look at the material (in this order):
MATLAB Onramp
Simulink Onramp
Stateflow Onramp
Simscape Onramp
Circuit Simulation Onramp
Power Electronics Simulation Onramp
Control Design Onramp with Simulink
The onramps are interactive, self-paced tutorial (around 2 hours length). It would be really beneficial to attend following (paid) trainings relevant to this topic:
MATLAB Fundamentals
Simulink for System and Algorithm Modeling
Stateflow for Logic Driven System Modeling
Modeling Physical Systems with Simscape
Power Electronics Control Design with Simulink and Simscape
Simulink Model Management and Architecture
Simulation-Based Testing with Simulink
Project details:
This project has been deveoped around a Texas instrument LED kit (codename: TMDSDCDCLEDKIT). It uses a F28069 ControlCard.
This application is interesting because:
  • The SEPIC is using medium to high switching frequency (100 kHz)
  • LEDs are current controlled using 20 kHz switching.
  • Filter design plays an important role in getting current and voltage signals as proper inputs to the controllers
Both controllers are PI controllers which were modeled, simulated tuned and verified within the Simulink platform. Because the converter was modeled appropriately, the PI parameters derived in simulation can be used directly on hardware with good results.
Workflow
This demo covers a typical power electronics development workflow, divided in 5 sections:
System Modeling: Model the converter and calculate the most efficient operating region
Thermal Analysis: Determine power losses and the thermal behavior of the converter
Control Design and Tuning: Design control algorithm based on time/frequency domain specification
Logic Design, Verification and Verification: Design supervisory logic and implement unit testing
Embedded Code Generation: Implement power electronic controls on an embedded platform
