Bodo's WBG Expert Talk

Talk to the experts! Join my virtual roundtable, focused on wide bandgap technology. Our goal is to keep the dialog going on, independent of any events that are hosted on fixed dates. These expert talks will build on the articles we published in the magazine, giving you the chance to ask questions to the experts out of the industry.

If you are interested in participating as an expert, please plan your article for the magazine. We will then invite you to one of the upcoming rounds. Our aim is to give as many companies as possible this opportunity, as we are sure that a wide variety of contributions is of value to everyone. Different speakers will bring new perspectives and approaches.

A huge thank you goes out to all participants of this successful edition of Bodo’s Expert Talk, of course especially to the speakers for making this such a lively discussion!

Recordings of all Expert Talk sessions are now available here.

We look forward to the next episode, coming to you on Wednesday, September 25th.
And don’t miss the current issue of the magazine – it is waiting for you in my archive!

Below you find the articles that are addressed in my last expert talk.

The AMZ racing team shattered the world record for electrically powered vehicle acceleration with an e-racer that darted from zero to 100 km/h in just 0.956 seconds. Called mythen, the vehicle built by ETH Zürich and Lucerne University students for the Formula Student competition shaved more than a third off last year’s record-setting time.

SiC MOSFETs are the power switch of choice for high-voltage and high-power applications in traction, distributed energy resources (DERs), onboard chargers (OBC), medical devices and more. SiC semiconductors outperform their silicon predecessors in key capabilities ranging from higher operating temperatures, breakdown voltage and switching speeds to lower RDS(on) and improved thermal performance and ruggedness.

Following closely behind the adoption of electric vehicles, new transportation markets are transitioning to electric mobility (or e-mobility) to achieve a sustainable, CO2-neutral future. From commercial electric vehicles to advanced air mobility, long-haul ships, and high-speed trains, new electrified vehicle concepts are emerging all around the world. But what does it take to enable industrial e-mobility? The latest innovations in silicon carbide technology can provide reliable, efficient, and cost-effective energy conversion and delivery.

If your power inverter measurements show an efficiency of more than 100%, or the measured values sound too good to be true, it could mean that either you found the holy grail, or -more likely- that there is a measurement error caused by phase shift. With the introduction of SiC and GaN semiconductors in inverter drives for EVs or DC/DC converters, the switching frequencies have increased considerably, and this makes electrical power measurement more challenging.

Modern agricultural techniques have been revolutionized by the integration of unmannedaerial-vehicle (UAV) drones, which are low-voltage battery-operated aircrafts. Smaller drones are utilized for terrain mapping and vegetation monitoring [1], while heavier, more robust variants are employed for tasks such as spraying and distributing fertilizers and insecticides [2] as well as disseminating seeds and feed [3] with payloads up to 50 kg loads [4].
