Description:DESCRIPTION: Field of the invention: [0001] The present disclosure generally relates to the technical field of DC-DC power converters, in specific, relates to a novel multi-source high gain integrated DC-DC converter topology that operates efficiently and reliably by integrating multiple power sources and providing high output voltage with minimal component stress. Background of the invention: [0002] DC-DC converters are widely used in various applications where it is necessary to convert one level of DC voltage to another. These converters are essential in systems where multiple voltage levels are required, such as electric vehicles, renewable energy systems, and industrial power supplies. In particular, for shipboard applications, where reliability and efficiency are paramount, DC-DC converters play a crucial role in maintaining consistent power supply for various onboard systems. Traditional DC-DC converter designs typically rely on either a boost or buck topology, depending on the required voltage conversion. However, these designs often face limitations in terms of efficiency, component stress, and the ability to handle multiple power sources. [0003] In shipboard environments, where power needs can vary significantly and multiple sources like solar panels, batteries, or fuel cells may be used, there is an increasing demand for converters that can integrate multiple inputs efficiently. Existing converter topologies, such as the standard boost converter, can be inefficient when dealing with low-voltage inputs or multiple power sources. Similarly, SEPIC (Single Ended Primary Inductor Converter) topologies, though useful for providing flexibility in step-up and step-down operations, can suffer from complex control strategies and increased losses due to higher component stress, particularly at higher power levels. [0004] Moreover, many traditional converters are prone to reliability issues when exposed to the harsh conditions often found in marine environments. These conditions include temperature variations, humidity, and electrical noise, all of which can affect the performance of power electronic components. Additionally, converters designed for such environments need to have high fault tolerance to ensure continuous operation, as unexpected downtime could have serious consequences for both safety and operational efficiency. [0005] Prior art systems, such as US20100213927A1, disclose multi-input DC-DC converters capable of integrating multiple power sources. However, these systems often involve complex circuitry, increased costs, and a high number of switching components, which increase both the physical size and maintenance requirements. Furthermore, these systems often do not address the challenge of maintaining high efficiency across a wide range of input voltages and load conditions, particularly in dynamic environments such as shipboard systems. [0006] A prior art DC-DC converter might disclose various topologies and methods for achieving high voltage gain and efficiency. However, many of these solutions do not address the specific challenges of integrating multiple sources with minimal component count and reduced stress on switching devices. Existing solutions often lack the necessary simplicity and reliability for high-power applications. Addressing these challenges, there is a need for a DC-DC converter that integrates a high-gain boost and SEPIC functionality, designed to efficiently manage power from multiple sources. Such a converter would enhance reliability, reduce component count, and improve efficiency in applications requiring robust power conversion solutions. [0007] By addressing the aforementioned challenges, there is a need for a DC-DC power converter that delivers high voltage gain, high efficiency, and fault tolerance while managing multiple power sources. Such a converter would be beneficial in improving the performance and reliability of power systems in various high-demand applications. [0008] By addressing all the above-mentioned problems, there is a need for a novel multi-source high gain integrated DC-DC converter topology that operates efficiently and reliably by integrating multiple power sources and providing high output voltage with minimal component stress. There is also a need for a multi-source high gain integrated DC-DC converter for electric shipboard applications that simplifies the construction and reduces the component count, leading to easier assembly, reduced cost, and lower maintenance requirements. There is also a need for a multi-source high gain integrated DC-DC converter topology that simplifies the construction and reduces the component count, leading to easier assembly, reduced cost, and lower maintenance requirements. [0009] There is also a need for a multi-source high gain integrated DC-DC converter topology that improves voltage regulation through the combined use of boost and SEPIC topologies, ensuring smooth power delivery even in fluctuating load conditions. There is also a need for a multi-source high gain integrated DC-DC converter topology that reduces stress on switching devices, leading to longer operational life and increased reliability in demanding environments such as electric shipboard systems. Further, there is also a need for a multi-source high gain integrated DC-DC converter topology with high energy density and efficient power conversion that makes it suitable for electric vehicles, renewable energy systems, and other high-demand applications.
