A group of students huddled around tables in a lab at N.C. State University one hot summer day in late July, peering through plastic goggles as they soldered components onto printed circuit boards. The finished boards would operate as power converters. Through the exercise, they were getting a crash course in wide bandgap power electronics, specifically, how silicon carbide and gallium nitride \u2013 two compounds that enable power electronics to operate highly efficiently \u2013 stacked up against silicon, which is the standard, less efficient material widely used in power electronics today.<\/p>\n

At the end of the exercise, students tested their boards with oscilloscopes, which display electric currents on a screen, and multi-meters, which measure them. \u201cAs you can see, the gallium nitride-based power converter operates at higher frequencies and efficiencies,\u201d said lab instructor and PhD student Alireza Dayerizadeh. The students looked on, nodding their head in agreement. You could practically see the wheels of their brain turning as the knowledge sunk in.<\/p>\n

Lab exercises such as these are just one component of the Research Experience for Undergraduates (REU), offered by PowerAmerica for 10 weeks each summer. The goal? To get students familiar with power electronics \u00a0– with a focus on wide bandgap, the backbone of PowerAmerica\u2019s mission. The institute strives to accelerate the development and adoption of these highly efficient power electronics systems, thus saving energy on a large scale and driving a stronger advanced manufacturing industry in the U.S. Getting the next generation of workers prepped to lead this charge is a vital part of fulfilling this goal.<\/span><\/p>\n

The REU program is unique in that it offers a crash course in a variety of skills not necessarily obtained in a traditional classroom. It\u2019s also unique in the students it attracts. The program pulls not just from four-year schools, but from community colleges in the surrounding region \u2013 reaching students who wouldn\u2019t otherwise have access to the research and labs at a large, well-funded research institution like N.C. State University, where the program is held and where PowerAmerica is based. For six weeks, REU students are also joined by high school students and teachers from surrounding counties \u2013 the \u201cpre-college\u201d component of PowerAmerica\u2019s summer education programs. This summer, 20 undergraduates, high school students and teachers participated.<\/span><\/p>\n

PowerAmerica also offers an additional program \u2013 the Undergraduate Research Scholars Program (UGRS) \u2013 that runs through the academic year. Students come from partner universities (PowerAmerica has 14<\/span> nationally) and are assigned to a Power-America funded university project.<\/span><\/p>\n

Not all the students are entering the electrical engineering field, either. This summer\u2019s class included students pursuing degrees in mechanical, computer science and aerospace engineering. The takeaway is that knowledge in power electronics is useful to a variety of research fields, and the diverse backgrounds only add to the program, said Pam Carpenter, PowerAmerica\u2019s Director of Education and Workforce Development.<\/span><\/p>\n

\u201cThere are so many different skillsets coming together that it sets the students up for success, and also helps PowerAmerica\u2019s academic researchers \u2013 it\u2019s a win win for everyone,\u201d Carpenter said.<\/span><\/p>\n

The course content for all programs is similar, although UGRS is administered remotely. In addition to weekly labs \u2013 featuring a wide variety of topics, from electric vehicles to wide bandgap to circuits to coding, as well as software like SolidWorks and MatLab – \u00a0students attend sessions on skills they may or may not have been taught in a classroom, like how to communicate their research and research ethics.<\/span><\/p>\n

Sean Clark, a Wake Tech student who will transfer into N.C. State\u2019s aerospace engineering undergraduate program this fall, applied for the program as a way to become more comfortable with electronics, hardware and wide bandgap. \u201cEverything overlaps, and I thought it was a great opportunity to learn more about all of them,\u201d he said. Clark said learning the ins and outs of software such as Simulink and MATLAB was probably the most beneficial part of the program, as well as learning presentation skills and how to effectively pitch his work.<\/span><\/p>\n

Hands-On Research<\/b><\/p>\n

Perhaps the most significant component of the curriculum for many students is getting assigned to assist with a project funded by either PowerAmerica or the FREEDM Systems Center<\/a>, another power electronics and power systems engineering research center research institute based at N.C. State (PowerAmerica and FREEDM merged their Education and Workforce programs in 2017).<\/span><\/p>\n

Undergraduate classes are often heavy on theory – \u00a0which is a critical component to any discipline – but adding the research experience helps students apply the theory in a research environment. \u00a0said Carpenter, the EWD program director. Participating in hands-on research with a team \u2013 including the project principal investigator, a graduate mentor and other students \u2013 helps the students learn skills like collaboration, teamwork, leadership and project management. It also gives them a frame of reference for other skills they learn in the program, like communicating their subject matter.<\/span><\/p>\n

\u201cResearch is often messy and ill-defined, so having a support system in place \u2013 like the type offered by our summer program \u2013 is significant to setting the student up for success,\u201d Carpenter said. What she means is that the research process can involve multiple failures and lots of experimentation, with a good bit of problem solving and critical thinking along the way \u2013 challenges that the students learn to confront effectively by learning from a more experienced team, as well as each other.<\/span><\/p>\n

Cristian Melara, a student in N.C. State\u2019s College of Electrical and Computer Engineering, studied more affordable ways to manufacture silicon carbide. He teamed up with PowerAmerica researcher Dr. Jay Baliga, a professor at N.C. State who has designed a silicon carbide wafer production process being utilized at the X-FAB Foundry in Lubbock, Texas. Over the summer, Melara tested the wafers being manufactured at X-FAB to see how well the process is working, cataloguing data to help with future wafer production. Working with a researcher who is pioneering the next generation of power electronics, and actually having a hand in testing his product, was invaluable, Melara said.<\/span><\/p>\n

\u201cThe more I went through this program, the more I really came to believe and understand that silicon carbide has the ability to revolutionize power electronics, and technology across the board. It\u2019s been a great experience,\u201d Melara said.<\/span><\/p>\n

Gregorio Sanford, a military veteran and former commercial diver who learned about the REU program when Dr. Carpenter, the program director, came to his class at Wake Tech Community College to encourage students to apply. He gained opportunities from the program that will be a valuable asset to his career down the road, namely the chance to submit a paper to the Advanced Power Electronics Power Conference on his project, dynamic wireless power transfer for industrial applications.<\/span><\/p>\n

\u201cIt\u2019s not every day that an undergraduate student gets an opportunity to submit, and be the lead author on, a scholarly article,\u201d Sanford said.<\/span><\/p>\n

Providing new opportunities for students that they can\u2019t get elsewhere is a major goal of the program, said Megan Morin, Carpenter\u2019s graduate assistant. \u201cAt the end, students will have built something, worked with something or done something they\u2019ve never done before.\u201d<\/span><\/p>\n

Program Successes + Looking Ahead<\/b><\/p>\n

Students leave the programs with a heightened understanding of power electronics, which is documented in exit surveys conducted by Carpenter and her team. For example, they saw a 30% improvement in the scores of students \u2013 both undergraduate and high school, as well as teachers – who were asked, \u201cWhat is a wide bandgap semiconductor?\u201d<\/span><\/p>\n

Morin is able to point to other program successes, too. \u201cWe\u2019re seeing students transfer in from community college to a four-year school, as well as a higher interest in graduate school after this program. We\u2019re seeing increased confidence, and the ability to speak effectively about their research.\u201d<\/span><\/p>\n

Back in the early \u201800s, the National Academy of Engineering defined the skills that would be needed for an engineer in 2020 to be successful. These include thinking outside the box, being creative, knowing how to communicate their work, and being able to adapt to the unexpected.<\/span><\/p>\n

Carpenter cites this standard when she talks about the goals for PowerAmerica\u2019s education and workforce program, and the importance of offering something students can\u2019t get elsewhere to equip them for jobs in power electronics and other advanced manufacturing fields. \u201cIt\u2019s important for our program to have the best, emerging practices for students preparing to be engineers,\u201d she said.<\/span><\/p>\n

It\u2019s also important to include everyone, Carpenter said. A quarter of this year\u2019s summer program students came from community colleges, and nearly half were from underrepresented populations. Carpenter would like to increase those numbers.<\/span><\/p>\n

In addition, Carpenter sees the programs as a way to introduce students to a career path in manufacturing they may not have seriously considered before.<\/span><\/p>\n

\u201cInterest in advanced manufacturing is an issue nationally, because the manufacturing that these students\u2019 parents and grandparents knew went away. So it\u2019s about changing the equation and building awareness and knowledge about the opportunities that are out there now,\u201d Carpenter said.<\/span><\/p>\n
