Abstract

In this paper, a low-cost flexible platform for photovoltaics is developed with a DSP-microcontroller arrangement for doing industrial control in an easy way, and the communication process between them is carried out with the McBSP bus. The control of the DC/DC boost converter and the d-q control approach of the 3-phase Voltage Source Inverter (VSI) have been established: the mathematical model of the plant is described and a decoupled control of the instantaneous active and reactive powers fed to the utility grid is achieved, allowing unitary power factor operation. Several measurements of the involved variables in the platform are described in order to evaluate the performance of the exerted control algorithms with the DSP-microcontroller arrangement, and the development of future complex algorithms and high computational tasks is validated.
