The past few months have left us with some startling images as the pandemic has pushed people to limit travel. Nearly empty freeways in Los Angeles, people driving around downtown New York City with ease, feats that many never thought they would ever experience. The side effect of this lack of travel has been a
The demand for more efficient and flexible recharging solutions is constantly increasing, especially aiming at leading the next generation of robotic systems towards greater autonomy.There are large companies with big plans to offer services based on drone fleets, and they are all eager to get beyond a significant operating challenge: the flight time of commercial
If the goal of moving to electric vehicles (EVs) is to reduce harm to the environment, then getting people out of individual cars and on electrified public transit should be a premier destination as well. While they may not look as sleek as the latest Tesla, electric buses are going places, too, despite similar range
GaN High Electron Mobility Transistors (GaN HEMT) have lower driving loss and shorter deadtime circuit benefits due to significantly reduced gate charge (Qg) and output capacitance (Coss) compared to Silicon MOSFETS. Therefore, GaN HEMTs show significant advantages over Silicon MOSFETs in high-frequency soft-switching resonant topologies such as an LLC resonant converter. With increased switching frequency
For EVs, the semiconductors used in traction inverters have a significant impact on efficiency, power density, and cooling requirements. The three-phase AC motors used in today’s EVs run at voltages up to 1,000V and switching frequencies up to 20 kHz. This is very close to the operational limits of the silicon-based metal-oxide semiconductor field-effect
Selecting an appropriate EMI filter is critical to achieving optimum size, performance, and cost. Different types of EMI filters provide different levels of suppression and have different characteristics. What works for one system might not work well in another. For this reason, it is essential to understand the considerations when selecting an EMI filter.
With silicon nearing its physical limits, electronics manufacturers are turning to non-traditional semiconducting materials, notably wide-bandgap (WBG) semiconductors. Some are adopting these technologies to hit cost and performance targets that otherwise can’t be reached, and while others seek to differentiate their products from their competitors’. Larry Spaziani, vice president of sales and marketing at
By switching to SiC MOSFETs, power system designers can significantly boost power density, lower switching losses, and improve thermal management in OBCs for electric vehicles. Power systems in electric vehicles (EVs), on-board and off-board battery chargers, and other energy storage systems are demanding greater energy efficiency to pack more power into... Read More!
Highly efficient ac/dc power supplies are key to the evolution of the telecom and datacom infrastructure, as power consumption grows rapidly due to hyperscale data centers, enterprise servers, or telecom switching stations. However, the power electronics industry has reached the theoretical limit of silicon MOSFETs. Meanwhile, recent gallium nitride (GaN) transistors have emerged as
Wolfspeed’s new line of 650V SiC MOSFETS, which incorporate the latest third-generation C3M silicon carbide (SiC) technology, join its established family of industry-leading sixth-generation C6D Schottky diodes, to deliver today’s design engineer exceptional performance, reliability, and efficiency...
