Research Objectives and Approaches: The objectives of this research are to develop key enabling technologies that will facilitate the design of three-port micro invertors which are able to convert DC power from conventional photovoltaic (PV) grid-connected systems into acceptable AC power. The approach is three-fold - (1) Investigating circuit operation and power stage design considerations of three-port micro invertors (2) Performing digital control design and studying the stability of the proposed three-port micro invertors by means of modern nonlinear theory (bifurcation and chaos theory), (3) Developing proper modeling procedures tailored to derive the small signal model of the three-port micro inverter.Intellectual Merit: The proposed research focuses on creating new concepts of three-port micro inverters, topology optimization, small signal modeling techniques, digital control, and nonlinear analysis. The aim is to reduce power losses and generate clean energy with greater efficiency. The research aims to investigate novel approaches to current energy conversion challenges, while satisfying the standard requirements of regular utility grids.Broader Impacts: Renewable energy sources and associated energy conversion technologies are imperative for a sustainable and prosperous future. The proposed research would improve the fundamental understanding of key technologies in power converter design, manufacture, and application. Not only would this research offer an innovative, cost-effective method for the generation of power anywhere in the world and thus contribute to universal economic and social development, but would also strengthen the power electronics curricula at the University of Central Florida (UCF) and Jordan University of Science and Technology (JUST) and attract the best students to the promising field of alternative energies.

研究目标和方法：本研究的目标是开发关键的使能技术，以促进三端口微型逆变器的设计，这些逆变器能够将传统光伏(PV)并网系统的直流电能转换为可接受的交流电能。该方法包括三个方面：(1)研究三端口微型逆变器的电路运行和功率级设计；(2)利用现代非线性理论(分叉和混沌理论)进行数字控制设计并研究所提出的三端口微型逆变器的稳定性；(3)开发适当的建模程序以推导出三端口微型逆变器的小信号模型。其目的是减少电力损耗，并以更高的效率生产清洁能源。这项研究旨在探索新的方法来应对当前的能源转换挑战，同时满足常规公用电网的标准要求。广泛的影响：可再生能源和相关的能源转换技术对于可持续和繁荣的未来是必不可少的。本文的研究将对电力变流器的设计、制造和应用中的关键技术有更深的认识。这项研究不仅将为世界任何地方的发电提供一种创新的、具有成本效益的方法，从而为全球经济和社会发展做出贡献，而且还将加强中佛罗里达大学(UCF)和约旦科技大学(JUST)的电力电子课程，并吸引最优秀的学生进入前景广阔的替代能源领域。
