Abstract
|
This article introduces a non-isolated three-port converter with a high voltage gain. The proposed converter employs a boosting technique that combines a switched capacitor and a coupling inductor, integrating both input ports into a single inductor. This not only enhances integration but also significantly increases power density. A remarkable advantage of this converter is the noticeable reduced voltage stress on switches and diodes, outperforming existing converters in adopting improved power density. Moreover, its low cost-per-watt ratio positions it as an economical solution for high-power density and low-power applications within standalone renewable energy systems. The effectiveness of this design is realised by the construction and successful validation of a 200-watt prototype, demonstrating stable output across load variations through practical experimentation.
