This study provides an overview of the advantages of current source topologies for multi-stage photovoltaic grid-connected systems, including improvements in component number, performance, power-decoupling techniques, efficiency, and frequency operation. It proves that current source systems are an attractive alternative for renewable energy applications.
Current source topologies have several advantages compared to conventional voltage systems. Their inherent voltage-boosting function, intrinsic short-circuit protection, no electrolytic capacitor, direct-current control, continuous input current, and high reliability make them exceptional candidates for power generation systems, particularly for photovoltaic applications. This study provides an overview of the current source topologies for multi-stage photovoltaic grid-connected systems by comparing the number of components, performance, power-decoupling techniques, efficiency, and frequency operation. The overview reveals gain, performance, energy quality and lifetime improvements, thereby providing current source systems as an attractive alternative for renewable applications.
