Description
The course will describe how to use the TMS320F28069 microcontroller from Texas Instruments for power electronics applications. The course is targeted towards beginners who are new to microcontroller programming and therefore, is ideal for electrical engineering undergraduates and graduate students who will be seeking their first job in the power industry. The course describes how a student can setup a basic home lab for the course, as this course is a hardware course and needs basic electronic equipment for hands-on experience. The course covers both theory and programming. The emphasis of the course is on creating projects and on programming the microcontroller. However, to make the material complete, the course deals with microcontroller architecture and describes the working of the processor and the peripherals.The course will begin with very simple examples such as how to make LEDs glow and flash. However, it will progress to more practical scenarios as found in power electronics applications where gating signals will be produced for practical converters. The course will also describe how the microcontroller can be used for control applications by feeding measured signals into the microcontroller and processing them. The course will use the Code Composer Studio IDE provided for free by Texas Instruments and also example projects and starter files provided through the C2000Ware package. The course will describe how necessary software can be be downloaded and how the student can interpret and understand the example projects.To be able to complete all examples in this course, the student will need to setup a home electronics lab which will cost around USD 150. Details of the components required are described in the introduction and all videos in the introduction are preview enabled.
