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