Abstract

This research paper proposes a novel design for a multi-source DC-DC converter that can control the output DC voltage obtained from multiple renewable energy sources. To achieve this, you would typically employ a power conditioning system or a DC-DC converter. The DC-DC converter would be responsible for regulating and controlling the output voltage based on the input from the renewable energy sources. The main objective of this research is to develop a converter design and control strategy that can effectively adjust the output DC voltage gained by multiple-source renewable energy systems. By employing a non-isolated double boost converter, the system can effectively regulate and control the bidirectional power flow, ensuring efficient energy transfer between the renewable energy sources and the storage system. This converter topology is particularly suitable for applications where bidirectional power flow and energy storage are essential components, allowing for effective management and utilization of the available energy resources and its additional advantages such as low profile, condensed component count, and double advancing ability. The converter employs a non-isolated double boost converter due to its compact structure, reduced component count, and double boosting capability. Additionally, an inverted controller strategy is assumed to handle disturbances originating from the source end. circuits models are established to derive the response of the controller, and simulations are conducted to validate the proposed control strategy. The results show a significant reduction in current ripple percentage and improved output voltage regulation. A converter is also implemented and tested, confirming the superior dynamic performance of the proposed converter. Furthermore, an adaptive optimal controller is developed to regulate voltage under demanding load conditions without requiring knowledge of converter dynamics.
