Wide Bandgap Semiconductor-Based Power Electronics for Aviation

October 14, 2022 by Fei Fred Wang

There is a growing trend in aircraft electrification, which can reduce green-house gas emissions, reduce audible noise, reduce maintenance needs, lower cost, and improve safety. Moving from mechanical, pneumatic, and hydraulic power to electric power requires architecture changes, more electric power, and improvements in electric power generation, distribution, and conversion. … [Read more...] about Wide Bandgap Semiconductor-Based Power Electronics for Aviation

Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics

June 20, 2022 by Jayathu Fernando; Nihal Kularatna; Shanima Silva; Sadeeshvara Silva Thotabaddadurage

Invention of the transistor in 1947 made a radical change to the path of the development of electronic products and systems. In the mid-1950s, integrated circuits (ICs) started evolving rapidly, creating miniaturized analog, digital and mixed signal circuits. By the 1960s to 1970s, microprocessors, memories and power semiconductors entered the electronic marketplace. During the … [Read more...] about Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics

Driven by Density, Efficiency at Low Cost, Power Integration Reaches New Heights

March 1, 2022 by Ashok Bindra

For decades, miniaturization has been the trend in the power supply world. Consumers have been demanding more functions from smaller systems with better performance and reliability at lower cost. Such advances are evident in today’s laptops, tablets, smartphones, industrial drives and a host of other consumer and industrial applications. To meet these demands, the power supply … [Read more...] about Driven by Density, Efficiency at Low Cost, Power Integration Reaches New Heights

Expert View: GaN Semiconductors Driving More Efficient Automotive Traction Inverters

December 1, 2021 by Jimmy Liu

Electric Vehicles (EVs) are continuing to grow their share of total vehicle sales as consumers, companies, and governments prioritize automotive electrification. Types of EVs include hybrid electric, plug-in hybrid electric, battery electric, and fuel cell vehicles. Today, EVs commonly use an ac permanent magnet or ac induction motor. A traction inverter is a critical … [Read more...] about Expert View: GaN Semiconductors Driving More Efficient Automotive Traction Inverters

Expert View: The Time for Software Defined Power Is Now

December 1, 2020 by Mark Adams

Reports on software defined power and its impact on current and future energy markets, data centers, new autonomous technologies, and computing power needs. The infrastructure is dominated by hardware and suppliers that are focused on devices that solve pinpointed problems—smaller, cheaper, and more efficient are typically the leading “values” of the solutions. That is what … [Read more...] about Expert View: The Time for Software Defined Power Is Now

A technology revolution is unfolding around us as every major mode of transportation is in some stage of electrification, whether on land, sea, or in the air. All of these transportation modes depend on electric machines that play critical roles in both propulsion systems as well as in a wide variety of accessory equipment. Fuel economy and reduced emissions of greenhouse gases and other pollutants are major driving forces for electrified transportation. Despite the significant differences between these varied transportation modes, they all share strong motivations to make their electric machines and adjustable-speed drives smaller, lighter, and more efficient. An excellent example of this trend for the power electronic drives is provided by comparing the drive units in the Tesla S (2012) and Tesla 3 (2017). As shown in the side-by-side views provided in Figure 1, the drive unit shrank in size from an enclosure that matched the size of its main traction motor to a much smaller unit that, at first sight, appears to be a non-descript end-bell attached to one end of the motor. Rather than focusing here on how this impressive reduction in mass and volume was achieved (addressed later in this article), the key point here is that similar technology trends are under way in many of the other transportation modes as well, making electrified transportation increasingly appealing and competitive in the process.
