In this third part of the C2000 Solar MPPT Tutorial, the software will be looked at in greater detail. This will entail a look at the Perturb & Observe algorithm, ADC code and timing code to ensure everything operates in a controlled manner.

C2000 Solar MPPT tutorial Pt/1
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.
