In 2008, the commercialization of the silicon carbide (SiC) MOSFET marked a major turning point for the power semiconductor market, representing its first significant development in decades. This technology was pioneered in electric vehicles (EVs) with the 2017 Tesla Model 3. The SiC MOSFET is a transistor that promises high power density, greater efficiency, and is less fallible to high temperatures.

One of the main reasons that electrification is so appealing in any industry is the reduction in operating costs offered by electric machines. This is especially true across the construction, agriculture, and mining (CAM) industries. Large machines with high uptimes, like mining haul trucks, can consume millions of dollars in fuel over their lifetime.

In April 2024, global energy, technology, and utility provider Hitachi Energy announced a US$1.5 billion investment program to ramp up global transformer production by 2027. IDTechEx's research into electrical grids indicates that transformers are a critical component and potential supply bottleneck for large-scale grid upgrades. These upgrades are essential as society shifts from a transportation sector fuelled by petrochemicals transported in tankers to a sector powered by electricity carried by wires.

Creating a circular economy is an essential sustainability target for numerous stakeholders in the supply chain: governments, brands, suppliers, and consumers. A key element of this is reducing plastic waste; the OECD estimated that over 350 million metric tonnes of plastic waste was generated globally in 2019

Thermal management for EV power electronics has long posed significant challenges. The ongoing shift from Si IGBT and SiC MOSFET to potentially GaN HEMT in the future results in higher junction temperatures and increased demand for die-attach materials in EV power modules. In traditional Si IGBT power modules, die-attach materials like Pb95Sn5 and Pb92.5Sn5Ag2.5 struggle to meet reliability requirements for packaging power devices in high-temperature applications due to creep-fatigue concerns.

Buses are the most common form of public transport worldwide and are an integral part of billions of daily commutes. From Mumbai to Amsterdam, buses offer cheap and accessible transportation for people to get to work, leisure, and a whole host of other destinations. Buses have been the workhorses of urban transport for almost a hundred years, and for most of that time, they have run on diesel engines.

Electric vehicle (EV) related news has been somewhat bleak in the first part of 2024; you will have heard a lot about the downturn in the EV market and OEMs scaling back plans. This might make one think that EVs are beyond their hype and that they will not be the solution of the future, but is that really the message we should be taking away? In this article, IDTechEx discusses the current statistics, the state of the market, and the outlook for the future.

eVTOL air-taxis could be the new efficient means of intercity travel with zero-emissions short flights. Whilst they may resemble helicopters, they could be far more cost effective and more environmentally friendly in the long run and are similar to aeroplanes in their rotor-enabled forward flight. With their electric propellors powered by batteries, new designs and innovations are broadening the market.

Automotive heads-up displays (HUDs) are awaited with great expectations and are set to revolutionize the automotive display industry. There are many reasons why this technology is anticipated with enthusiasm, namely its potential to positively impact driver behavior on the road, allowing for further vehicle customization and enhancing communication between the front seat passenger and the vehicle.
