Supplement for Undergraduate Research Support

提出的主要任务是开发用于先进低压(1.5-5伏)微电子电源的小型化、高效的功率磁元件的理论和技术，这些元件将作为具有非常高的效率(95%)和非常高的功率密度(每立方英寸100瓦)的板级“元件”分布。这项技术至关重要，因为事实证明，制造电力变压器和电感的传统方法不足以实现可重复且经济高效的小型化、高性能组件。要开发的是交替的磁配置、电气和机械模型，这些模型在电路和系统级别上很有用，并用于模拟、制造技术和强调成品率的设计方法。开发了电力电子工程中急需的计算机辅助设计工具--电力电子电路与系统仿真器。要实现的基本特征是行为和分层建模、事件驱动的调度、可变和多个时间步长以及开关模式网络的高效数值算法。此外，还包括电力电子元件、功能模块和转换器拓扑的模型。将建立课程和实验室，以培养能够从事电力电子事业或进行研究的学生。

The primary task proposed is to develop the theory and technology to realize miniaturized, efficient power magnetic components for use in advanced low-voltage (1.5 - 5 Volts) microelectronic power supplies, which will be distributed as board-level "components" having very high efficiency (95%) and very high power density (100 Watts per cubic inch). The technology is essential because conventional methods to fabricate power transformers and inductors prove inadequate to realize miniaturized, high-performance components reproducibly and cost- effectively. To be developed are alternate magnetic configurations, electrical and mechanical models that are useful at circuit and system levels and for simulation, fabrication techniques, and design methodology with yield emphasis. Also proposed is the development of a Simulator for Power Electronics Circuits and Systems, a much-needed CAD tool in power electronic engineering. Basic features to be realized are behavioral and hierarchical modeling, event-driven scheduling, variable and multiple time steps, and efficient numerical algorithms for switched-mode networks. Models for power electronic components, functional blocks, and converter topologies are also included. Curriculum and laboratories will be established to produce students capable of pursuing a career or performing research in power electronics.
