ECE 411- Power Electronics

Course Meeting: M 5:00 pm to 7:40 pm (Fall '22)

Course Description: Power electronic circuits and switching devices such as power transistors, MOSFETs, SCRs, GTOs, IGBTs, and UJTs are studied. Their applications in AC/DC, DC/DC, DC/AC, and AC/AC converters as well as switching power supplies and UPS systems are explained. Simulation mini-projects and lab experiments emphasize power electronic circuit analysis, design, and control.

Course Purpose: Power electronic converters are used in different applications from low-power personal computers, home appliances, and automotive systems, to medium-power telecommunication systems, switching power supplies, and industrial motor drives, to high-power active filters and flexible AC transmission systems for terrestrial power systems. In fact, power electronics provides the basis for a variety of new electrical circuit architectures that allow substantial improvements in performance and flexibility.

The purpose of this introductory course in power electronics is to give an overview of the major aspects of switching power devices and circuits. Operating principles of different electronic switches as well as converters such as rectifiers, choppers, and inverters are presented. Applications of power electronics are explained. Guidelines to design proper switching circuits are also established.

ECE 412/512- Hybrid Electric Vehicle Drives

Course Meeting: M 5:00 pm to 7:40 pm (Spring '22)

Course Description: Designed with support from the TUES program of the National Science Foundation (NSF), this course provides students with a strong academic background and hands on laboratory-based experience focused on energy-efficient hybrid electric vehicles (HEVs). Fundamentals of drivetrains for electric vehicles and hybrid electric vehicle drives are studied with a brief introduction to different machine topologies. Applications of semiconductor switching circuits to adjustable speed drives, robotics, and traction applications are explored. Selection of motors and drives, calculating the ratings, speed control, position control, starting, and braking are also covered. Simulation mini-projects and lab experiments are based on the lectures given.

Course Purpose: The purpose of this design course in hybrid electric vehicle technologies is to use the HEV and EV as a platform to integrate fundamental concepts from electric machines, micro-controllers, signal processing and control theory. It will give an overview of the major components of powertrains in Hybrid, Plug-in Hybrid and Electric Vehicles. Operation of the electric motor drive (including electric machine and power electronics) will be explored in the context of power, torque and performance in this high-efficiency system. It will evaluate the design electric machines, control of adjustable speed drives for electrified transportation systems with industry-relevant examples and problems.

IPRO 497: Electrified Transportation for Land and Space

Course Meeting: T 5:00 pm to 7:40 pm (Spring '22)

Location: Kaplan Institute (KI 107, Tell Labs)

Course Purpose: Automotive companies such as Tesla and Faraday Future, Unmanned Aerial Vehicles (UAVs), autonomous vehicles are some of the areas that have made giant strides in recent years. Electrification has allowed fast and powerful operation in addition to substantial benefits in efficiency. However, this area is still in development stage and has been very receptive to advanced design and innovation. This has created a major demand for engineers with practical, hands-on experience in system design and hardware development, leadership and teamwork.

In this IPRO, students work in interdisciplinary teams towards two international student competitions- the Formula electric SAE racecar competition and the NASA Robotic Mining Competition. Students get an opportunity to design and implement the two vehicles and compete in the international competition to be held in New Hampshire and Kennedy Space Center (Florida), respectively.

The team working on the design and implementation of a Formula SAE electric racecar towards the international SAE Formula Hybrid competition held in New Hampshire in May each year. From an industry standpoint, petroleum prices continue to rise every year and consumers are hard pressed to find alternatives to their gasoline-hungry vehicles. Through this project, students explore and develop the same cutting-edge automotive technology that will be making its way into many markets in the next few years. The vehicle will be judged on design innovation, endurance and overall system engineering.

The team working on a NASA Robotic Mining Competition towards the international competition held at the Kennedy Space Center in Florida in May each year. In this competition, students will design and build a mining robot that can traverse a simulated Martian terrain. The robot must excavate Martian soil the basaltic regolith simulant and move the excavated mass into the collector bin to simulate an off-world resource-mining mission. The robot will be judged on completion of task, design innovation, size and weight. It must consider design and operation factors including dust tolerance, communications, energy management, and autonomous operation.

In addition to the Idea shop at Kaplan Institute, the team will have access to the research capabilities of the Electric Drives and Energy Conversion lab in the department of electrical and computer engineering and the SAE garage. The team will also develop relationships with technical sponsors and commercial partners, which will allow access to necessary software, hardware, material and services for the implementation.

IPRO 497: Smart Tech for Assistive Technologies

Course Meeting: MW 1:35pm - 4:45pm (Summer '22)

Location: Kaplan Institute (KI 107, Smart Tech Labs)

Course Purpose: We live in an era with unprecedented access to data and technology where technology has ceased to be a novelty and has become part of everyday life. That means that computing and technology can be used to improve everyday life. Using Smart Technology or IoT devices can be used to improve quality of life considerations. Each person brings a unique insight to life on how to use technology to tackle matters they deem important. This IPRO will investigate using Smart Technology to address quality of life issues and investigate how to create equity using technological solutions. Students will work in small groups on a topic that was selected by them and vetted by the instructor. There will be short instructional modules explaining resources and certain technology. There will be lab and open work time with weekly to bi-weekly internal presentations for feedback amongst the class members, instructors, and any guest/mentors
