0138275 BatarsehDescription: This project supports a cooperative research project between Dr. Issa Batarseh, School of Electrical Engineering and Computer Science, University of Central Florida, Orlando, Florida and Dr. Ahmad Harb, Department of Electrical Engineering, Jordan University of Science and Technology in Irbid, Jordan. This project deals with bifurcation and chaos theory for power electronic circuits. Most of today's dynamic modeling methods applied in power electronic converters is based on either linear ripple approximation, assuming that the natural frequencies of the converter are well below the switching frequency, or on time-averaging the output or the duty ratio function, effectively eliminating the sampling effect of the switch. These methods fail to predict the system behavior at high frequencies. The accuracy of these models degrades as the modulation frequency approaches one-half the switching frequency; hence they fail to predict the instability occurring in this region of frequencies. The objective of this joint research project is to investigate the application of bifurcation theory to newly developed modern high frequency dc-dc converters. The project will focus on two groups of power electronic circuits: I) parallel-input/series-output two-module boost-derived DC-DC converter with mutually coupled output filter inductors, and II) Single-stage Power Factor Correction (PFC) circuits. Scope: This project enables the US and Jordanian scientists to pool their complementary expertise and resources in providing a new approach to analyzing the behavior of power electronics converter systems. One US graduate student from UCF will participate in this international collaborative project. The project meets the INT objective in supporting workshops where mutual benefits and dissemination of information is likely to result. This project is funded by the Office of International Science and Engineering and the Division of Electrical and Communications Systems.

0138275 Batarseh 描述：该项目支持佛罗里达州奥兰多市中佛罗里达大学电气工程与计算机科学学院 Issa Batarseh 博士和约旦科技大学电气工程系 Ahmad Harb 博士之间的合作研究项目约旦伊尔比德。 该项目研究电力电子电路的分岔和混沌理论。 当今电力电子转换器中应用的大多数动态建模方法都基于线性纹波近似（假设转换器的固有频率远低于开关频率），或者基于对输出或占空比函数进行时间平均，从而有效地消除了开关的采样效果。这些方法无法预测高频下的系统行为。当调制频率接近开关频率的一半时，这些模型的精度会降低；因此他们无法预测该频率区域中发生的不稳定性。 该联合研究项目的目的是研究分岔理论在新开发的现代高频 DC-DC 转换器中的应用。该项目将重点研究两组电力电子电路：I) 具有互耦输出滤波电感器的并联输入/串联输出双模块升压衍生 DC-DC 转换器，以及 II) 单级功率因数校正 (PFC)电路。范围：该项目使美国和约旦科学家能够汇集互补的专业知识和资源，提供一种分析电力电子转换器系统行为的新方法。 一名来自 UCF 的美国研究生将参加这个国际合作项目。该项目满足了 INT 支持研讨会的目标，在这些研讨会上可能会产生互惠互利和信息传播。 该项目由国际科学与工程办公室和电气与通信系统部资助。
