Abstract

This research paper introduces an avant-garde poly-input DC-DC converter (PIDC) meticulously engineered for cutting-edge energy storage and electric vehicle (EV) applications. The pioneering converter synergizes two primary power sources-solar energy and fuel cells-with an auxiliary backup source, an energy storage device battery (ESDB). The PIDC showcases a remarkable enhancement in conversion efficiency, achieving up to 96% compared to the conventional 85-90% efficiency of traditional converters. This substantial improvement is attained through an advanced control strategy, rigorously validated via MATLAB/Simulink simulations and real-time experimentation on a 100 W test bench model. Simulation results reveal that the PIDC sustains stable operation and superior efficiency across diverse load conditions, with a peak efficiency of 96% when the ESDB is disengaged and an efficiency spectrum of 91-95% during battery charging and discharging phases. Additionally, the integration of solar power curtails dependence on fuel cells by up to 40%, thereby augmenting overall system efficiency and sustainability. The PIDC's adaptability and enhanced performance render it highly suitable for a wide array of applications, including poly-input DC-DC conversion, energy storage management, and EV power systems. This innovative paradigm in power conversion and management is poised to significantly elevate the efficiency and reliability of energy storage and utilization in contemporary electric vehicles and renewable energy infrastructures.

摘要

本研究论文介绍了一种精心设计的前卫多输入直流-直流转换器（PIDC），用于前沿的储能和电动汽车（EV）应用。这种开创性的转换器将太阳能和燃料电池这两个主要电源与辅助备用电源——储能设备电池（ESDB）协同起来。PIDC的转换效率有显著提高，传统转换器的效率为85%-90%，而它能达到96%。这一显著提升是通过一种先进的控制策略实现的，并通过MATLAB/Simulink仿真以及在100W测试台模型上的实时实验进行了严格验证。仿真结果表明，PIDC在各种负载条件下都能保持稳定运行和卓越效率，当ESDB断开时峰值效率为96%，在电池充电和放电阶段效率范围为91%-95%。此外，太阳能的整合使对燃料电池的依赖减少了多达40%，从而提高了整个系统的效率和可持续性。PIDC的适应性和增强的性能使其非常适合广泛的应用，包括多输入直流-直流转换、储能管理和电动汽车动力系统。这种电力转换和管理的创新模式有望显著提高当代电动汽车和可再生能源基础设施中储能和利用的效率及可靠性。
