Power Electronics - EECS 418
Meeting the future's energy and environmental challenges will require the efficient conversion of energy. For example, renewable forms of energy must be integrated with the nation's 60Hz AC electricity grid. Furthermore, hybrid electric vehicles require efficient energy conversion in order to improve their fuel economy over conventional vehicles. Power electronic circuits are a key component of these systems. Power electronic circuits are circuits that efficiently convert one form of electrical energy (e.g., AC, DC) into another.
This course will discuss the circuit topologies used to efficiently convert AC electrical power to DC, DC power from one voltage to another, and DC power to AC power. The components used in these circuits (e.g., diodes, transistors, capacitors, inductors) will also be covered in detail. A key aspect of power electronic circuits is the control algorithm used to achieve the desired behavior (e.g., output voltage regulation), and so control theory as it applies to these circuits will also be discussed.
Electric Machinery and Drives - EECS 419
In the struggle to address today’s energy and environmental challenges, many potential solutions require electro-mechanical energy conversion. Examples include electric propulsion drives for electric and hybrid electric vehicles, generators for wind turbines, and high-speed motor/alternators for flywheel energy storage systems. Each of these systems contains: an electric machine operating either as a motor, a generator, or both; a power electronic circuit which interfaces the machine to a power supply or an electrical system; and a controller which measures electrical and mechanical quantities and uses this information to control the power electronic circuitry.
In this course we will cover fundamental electromechanical, power electronic, and control theory in the context of electric drive systems. The capabilities and limitations of different types of electric machines (e.g., permanent magnet, induction) in various drive applications will be covered. MATLAB® Simulink® models will be used throughout the course to give students exposure to the dynamic behavior of these systems. Finally, a three-hour lab will be held each week to give the students hands-on experience with electric machines and drives.
Power System Design and Operation - EECS 463
The course will establish the basic principles of power system operation and control, under normal conditions and when faults occur. It will develop the models and tools necessary for analysing system behavior, and provide opportunities for using those tools in design processes. Optimal generation dispatch will be developed, and electricity market implementation issues addressed. The impact of renewable generation on power system operation will be considered.
Grid Integration of Alternative Energy Sources - EECS 498 [FLYER]
The course will present a variety of alternative energy sources, along with energy processing technologies that are required for power system connection. System integration issues will be addressed, with consideration given to impacts on current power system design philosophies and operating principles. Topics will be covered at a level suited to establishing a broad understanding of the various technologies, and of the associated system implications.
Power Semiconductor Devices - EECS 598 [FLYER]
Power devices are at the heart of all modern electronics, from the grid and renewable energy sources to fuel-efficient vehicles and mobile devices. In this course we will cover design and operating principles of semiconductor switches and rectifiers for discrete and integrated power electronics. Devices to be discussed include power MOSFET, IGBT, HEMT, thyristors, Schottky and PiN diodes, as well as new and emerging device architectures. We will look at power semiconductor substrates, device fabrication, packaging, and thermal modeling. Students will learn how to model power devices using commercial software and will do a group presentation on a topic of their choice. This course is pre-approved as a Flexible Technical Elective for undergraduate EE majors and an EECS elective for CE majors. Within the ECE graduate program, this course has been pre-approved as a Major Course for Solid State/Nano and as category "E" for VLSI/IC and Power and Energy.
Analysis of Electric Power Distribution Systems and Loads - EECS 598 [FLYER]
This course covers the fundamentals of electric power distribution systems and electric loads. Most power system courses focus on analysis of transmission systems; however, with increased amounts of distributed generation (photovoltaics, small-scale wind), distributed storage, and controllable loads, it has become more and more important for researchers and power industry professionals to understand power distribution systems. We will start with an introduction to distribution grids, including their components, typical topologies, and operational strategies. We will then study power flow in distribution grids and distribution transformers. Additionally, we will discuss the fundamentals of electric loads, including electric load modeling, analysis, and control methodologies. Course material will be from a combination of textbooks and recent research articles in the field. In addition to technical topics, we will also discuss energy economics and policy related to distribution grids and loads. All students will conduct an individual research project on a topic related to the course material.
Power Systems Markets and Optimization - EECS 598 [FLYER]
This course covers the fundamentals of electric power system markets, and the optimization methods required to solve planning and operational problems including economic dispatch, optimal power flow, and unit commitment. The course will highlight recent advances including convex relaxations of the optimal power flow problem, and formulations/solutions to stochastic dispatch problems. Problems will be placed in the context of actual electricity markets, and new issues, such as incorporation of renewable resources and demand response into markets, will be covered. All students will conduct an individual research project.
Electromechanics - EECS 598 [FLYER]
It is imperative that society finds new solutions to the generation and usage of energy. Many of the current approaches to achieving these objectives (e.g., wind power, electric and hybrid electric vehicles, energy harvesting) require efficient conversion of mechanical energy into electrical form, and vice-versa. In this course we will discuss the analysis and design of electromechanical devices, with an emphasis on power and energy applications. Devices based upon mechanical forces generated by both electromagnetic fields and materials with electromechanical material properties will be considered. In addition to homework assignments, midterm, and final, the course will have a final design project. This project will be selected by the student, and will be approved by the instructor provided it has significant electromechanical design content.
Advanced Topics in Electric Drives - EECS 598 [FLYER]
In the struggle to address today’s energy and environmental challenges, many potential solutions require electro-mechanical energy conversion.
