A closer look at semiconductor packaging considerations in EVs One of the most critical decisions to be made at the earliest stage of designing a new power converter concerns the packages used for the semiconductors, as pretty much every other aspect of the design hinges on their physical form. This is especially true for the main… Read more »

EMC for EVs: Understanding electromagnetic compatibility
Engineers who design power electronics supplied by the mains have had to contend with meeting various electrical noise and safety standards for decades now, but their counterparts in the automotive industry were mostly free to do as they pleased. This was mainly because 12 V isn’t considered a shock hazard and cars are effectively rolling… Read more »
The need for high-temperature capacitors in DC link buses
Sponsored by Knowles Precision Devices Today’s advancements in power electronics are reaching all-new highs in performance. In the quest for increasing efficiency and power density of converters and inverters, manufacturers are looking to use WBG semiconductors, such as gallium nitride (GaN) and silicon carbide (SiC), for making metal-oxide semiconductor field-effect transistors (MOSFETs), metal-semiconductor field-effect transistors (MESFETs)… Read more »
UnitedSiC announces SiC FETs with RDS(on) of less than 10 mohms
Range and horsepower may get the headlines, but to powertrain designers, drain-source resistance, also known as RDS(on), is a sexy spec. Those in the know are excited over the news that UnitedSiC, a New Jersey-based manufacturer of silicon carbide (SiC) power semiconductors, is introducing four new SiC field-effect transistors (FETs) that boast RDS(on) levels of… Read more »
Why did Porsche go to the trouble of designing an 800 V Taycan EV?
How higher-voltage battery packs enable faster charging ecosystems Porsche took on a considerable engineering challenge when it decided to design an 800 V EV system for the Taycan, because nearly every other hybrid and EV in the world operates at 400 V or less. There simply was not a wide range of high-voltage off-the-shelf parts… Read more »

A closer look at advances in power PCBs
In just the last few years there have been some major improvements in printed circuit board technology that are especially relevant to power electronics. Arguably the most important of the recent advances is the development of new board substrates that can withstand higher temperatures, along with metal cores for improved heat transfer, and the ability… Read more »
Cree to build silicon carbide device manufacturing facility in New York
Silicon carbide manufacturer Cree plans to build a new manufacturing facility in Marcy, New York. The fabrication facility for 200 mm power and radio frequency wafers, which will have a footprint of 480,000 square feet upon completion, will help increase capacity for the company’s Wolfspeed SiC and GaN business. The facility is the result of… Read more »
Delphi and Cree partner on silicon carbide devices
Delphi Technologies and Cree have partnered to use Cree’s silicon carbide semiconductor technology in Delphi’s electronic systems for EVs. The partnership will combine Cree’s silicon carbide-based metal-oxide-semiconductor field-effect transistors (MOSFETs) with Delphi’s traction drive inverters and DC/DC converters and chargers, aiming to extend driving range and provide faster charging times. To start, Cree’s MOSFETs will… Read more »
