Challenges and benefits of moving from silicon to GaN in EV power electronics: WEBINAR

As vehicle electrification increases, so does the requirement of power semiconductors to provide highly efficient power conversion at increasingly higher switching frequency. A move from traditional Si to WBG, in particular Power GaN FETs, coupled with Cu clip-bonded package technology instead of traditional wire bonded D2 and TO packages can address the demands of electrification… Read more »

BASF says its Ultramid polymer meets heat and corrosion protection requirements for EV powertrains

With the development of its heat-stabilized Ultramid B3PG6 BK23238, BASF is expanding its product portfolio of polyamides for the high temperature range. The new P-stabilization offers a heat resistance of up to 190° C and prevents galvanic corrosion on electrical components due to its low-halogenide and metal-free stabilization. The polyamide, reinforced with 30% glass fibers,… Read more »

Can the global battery supply chain keep up with anticipated EV demand?

As global demand for EVs increases, many are questioning the adequacy of the existing battery supply chain. A recent article in Transport Dive discusses the challenges involved in building a global supply chain that can keep up with the anticipated growth in EV production. Elon Musk said in October that a shortage of battery cells… Read more »
