Abstract

Photovoltaic (PV) generators are a good option for producing electricity in a decentralized and sustainable way. The development of enhanced power electronic interfaces and training of HQP is still in high demand. This paper discusses the digital implementation of the required control loops of a typical 2-stage PV interface using a low power renewable energy developer´s kit (REK). Experimental results demonstrate the effectiveness of the selected techniques and implementation in steady-state and transient conditions.
