In this competition, we proposed the idea of using the wide bandgap devices (GaN) to implement a high performance, high power density 500-W digitally controlled PV inverter. In this project, a two-stage grid-connected inverter was proposed for photovoltaic (PV) systems. The proposed system consisted of a three-phase boost converter which tracks the maximum power point of the PV system and a single-phase inverter with an LCL filter to transfer the PV energy to the grid. The ECIE team was awarded the grand prize based on their new innovation and practical ideas.
- Input: 48 Vdc nominal from a specified PV panel.
- Output: Vout: 110 Vac; Pout: 500 W.
- The peak efficiency was 98.15%.
