Abstract
Module-level power electronics represents a promising approach to locally optimize power extraction from bifacial modules under non-uniform and time-varying illumination, and to decouple individual PV units from the rest of the generator. In this context, this work presents the design, implementation, and preliminary experimental validation of a GaN-based DC-DC boost MPPT converter specifically developed for bifacial PV submodules. A detailed numerical thermal model of the converter has been carried out, and compared to data, to assist the design. The DC-DC boost converter has been interfaced to a 20-cell silicon heterojunction bifacial module. It performs local maximum power point tracking independently of the electrical conditions imposed at its output as desired. Indoor and outdoor characterizations have been carried out to test the electrical and thermal behavior of the power converter.
