As one of the most basic and fundamental components in electronics, capacitors are used in large numbers across a variety of designs. A key requirement for applications such as mobile phones, IoT devices, and high-performance compute applications is to effectively address last mile power delivery challenges, such as high-frequency power demands for the high-performance processors that they are inevitably based on. While traditional multilayer ceramic capacitors (MLCCs) have fulfilled the requirements thus far, stricter constraints on power density are challenging the continued usage of the existing model.

For one to be a good power electronics engineer one must know a lot about a lot. Power electronics engineers obviously have to know about power conversion circuits and topologies. But, we must also have a basic understanding of semiconductor physics to truly understand how our power switching devices work and how to make best use of them. We must have a deep understanding of magnetics and magnetics devices. We have to know about all different types of capacitor technologies, the characteristics of each, and where each fits in our power converter designs. We must know analog and digital circuit design to create not just analog controllers but all sorts of monitoring and protection circuitry. We have to know a fair amount about control theory to properly design our controllers. We have to know product safety standards and practice. We have to know EMI standards and how to control unwanted electromagnetic emissions both by design and by mitigation after the fact. We have to understand heat transfer and thermal management. I believe that good power electronics engineers must have a greater breadth and depth in more technical areas than some other engineering specialties.

In this article, the factors impacting gallium nitride (GaN) adoption are examined, as well as how they are being addressed and overcome. The key issues that we’ve heard from customers over the last 13 years that Efficient Power Conversion Corp. (EPC) has been in volume production fall into the following categories: small size and thermal management; reliability concerns; ease of use; and cost. The barriers to mass adoption of GaN power devices are rapidly falling and early adopters will have a distinct advantage over their competitors.

The progress made in wide bandgap (WBG) semiconductors has resulted in rapid miniaturization and increased efficiency of power converters. However, the improvements in magnetic components, such as inductors and transformers, have not kept pace with these advancements [1] , [2] , [3] . Although advances in WBG devices, novel topologies, control schemes, and hardware fabrications have greatly improved circuit efficiency and power density, the bottleneck now lies with magnetic components [4] , with magnetics accounting for more than 30% of the cost and more than 30% of the loss in almost all power converters [5] . Magnetics design has become a critical issue for power electronics as trends towards high efficiency and high power-density.

In this article, we present an overview and latest BRUSA Elektronik AG [1] achievements related to the inductive charging system (ICS). Moreover, our aim is to raise awareness of BRUSA contributions to ICS, both in the academic world, as well the industry. Recently, it was uncovered that our efforts were not recognized in recent review papers on wireless inductive charging of electrical vehicles (EVs) [2] , [3] , [4] , even though our company was the first to demonstrate a working ICS for BMW [1] .

Every year the IEEE Awards Board recommends a select group of recipients to receive IEEE’s most prestigious honors. These are individuals whose exceptional achievements and outstanding contributions have made a lasting impact on technology, society, and the engineering profession. This year at the IEEE Vision, Innovation, and Challenges Summit (VICS) and Honors Ceremony in Atlanta, GA, USA, there were several recipients of the IEEE medals. Amongst them were Vinton “Vint” Cerf, widely known as the “Father of the Internet,” remote sensing pioneer Melba Crawford, National Instruments (NI) Cofounder James Truchard, and robotics and artificial intelligence (AI) gurus Rodney Brooks and Lydia Kavraki. Other notable names in the power and semiconductor arena included Canadian Professor Kamal Al-Haddad, silicon carbide (SiC) material pioneer Hiroyuki Matsunami, and superjunction power devices researchers Tatsuhiko Fujihira, David James Coe, and Gerald Deboy.
