Developing DC-DC Converter Control in Simulink

Overview

In this webinar, we will use a SEPIC circuit topology to show how to model and simulate a DC-DC converter that powers a strip of LEDs. Using Simulink® and Simscape Electrical™, MathWorks engineers will show how to develop, simulate, and implement a controller that maintains desired output voltage in the presence of input voltage variations and load changes to achieve fast and stable response. The control algorithms will be used to generate embedded code optimized for implementing on a Texas Instruments™ C2000™ microcontroller. The demonstration will conclude with hardware-in-the-loop (HIL) testing of the microcontroller using a Speedgoat real-time target machine.

Highlights

• Modeling and simulating passive circuit elements, power semiconductors, and varying power sources and loads
• Simulating the converter in continuous and discontinuous conduction modes
• Determining power losses and efficiency of the converter
• Tuning the controller to meet rise time, overshoot, and settling time
• Generating C code from the controller model for implementation on a Texas Instruments™ C2000™ microcontroller
• HIL testing using a Simscape Electrical model deployed to as FPGA implemented in a Speedgoat real-time target machine
