This chapter discusses advances in power electronics as one of the primary enablers of the unprecedented growth of renewable energy sources on the electrical power grid over the past several decades along with the current evolution toward ever-higher levels of electrification, the process of replacing fossil fuels with renewable sources of energy that are delivered over the electrical grid. Furthermore, the critical role of energy technologies toward a more electric and sustainable future with an emphasis on opportunities and challenges facing wide-bandgap power semiconductor devices is presented. The chapter also covers future research and development directions in materials science, characterization, and physical electronic device architectures to push the limits of power electronics to utilize wide-bandgap semiconductors that go beyond Si and SiC. The areas that still need development are discussed along with potential high-impact application areas.
