This series of four posts will cover a project build for a C2000 Solar MPPT Tutorial. The Maximum Power Point Tracker (MPPT) circuit is based around an interleaved synchronous buck circuit topology. The microcontroller used is the Texas Instruments (TI) C2000 family, the C2000 Launchpad is used which has a TMS320F28027 chip on-board. Considerable research was carried out on this project, as there was no prior knowledge of the C2000, all the relevant peripherals were tested separately and then brought together and tweaked for the final code. TI provides all the documentation required, which can be found here and for this tutorial the ADC, ePWM and the F2802x Peripheral Driver Library Users’ Guide were referenced.
In this Power Factor Correction PFC tutorial, a basic PFC circuit and the calculations used to design the circuit will be demonstrated.
In this PID tutorial C code example Pt/2, the basic concept of a Boost PID controller will be explored. All the PID controller C code is stepped through, as well as some basic concepts for testing and tuning the controller. The final C code example can be downloaded via the link at the end of the article.
In this PID tutorial C code example Pt/1, the basic concept of a PID controller will be explored. The full example code is implemented on a Stellaris LM3S6965 microcontroller, and is used to control a simple boost converter circuit, regulating the voltage with a change in load resistance. The boost circuit is not covered in-depth in this tutorial, but the fundamentals of a boost circuit are covered.
Stellaris ADS1118 tutorial will show how a Stellaris LM3S6965 is interfaced with a ADS1118 16 bit ADC using the SPI bus.
In part 2 of this MSP430 state machine project, I will overview the state machine logic, as well as covering the C programming code.
MSP430 state machine project tutorial demonstrates a simple state machine, with a human interface consisting of 4 buttons, an LCD and some interfacing electronics.
