Developing and Implementing Digital Control for Power Converters
Using a buck-boost power converter example, this talk explains how Simulink® and Simscape Electrical™ are used 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 presentation covers:
- Modeling passive circuit elements, power semiconductors, and varying power sources and loads
- Simulating the converter in continuous and discontinuous conduction modes
- Determining power losses and simulating thermal behavior of the converter
- Tuning the controller to meet design requirements such as rise time, overshoot, and settling time
- Generating C code from the controller model for implementation on a Texas Instruments™ C2000™ microcontroller
