The electric vehicle market is snowballing and has even proved resilient to COVID-19 related shutdowns, seeing year-on-year growth throughout 2020. Within the EV market, increases are seen in battery capacity, range, charging rates, wide bandgap semiconductors, and high-performance traction motors.
While lithium-ion batteries have long since used graphite as an anode material, its lack of density is a problem for next-gen high energy applications like electric vehicles. One potential replacement material is silicon, and significant research efforts are underway to commercialize so-called lithium-silicon batteries.
Embedded systems are more ubiquitous than we realize, but what exactly are they, and where are they used? This article compares embedded systems to desktop/laptop PCs, considers their advantages and disadvantages, and looks at some applications and examples.
The US semiconductor manufacturer GlobalFoundries has turned down Intel's intention for a takeover. The company intends to continue operating independently and is aiming for global expansion with new production facilities.
The two research teams from the LaserApplicationCenter and the Materials Research Institute Aalen are working on the question of how they can improve the fast-charging capability of lithium-ion batteries - for example, to reduce annoying waiting times at charging stations for electric cars.
Power Integrations, an expert in high-voltage integrated circuits for energy-efficient power conversion, announced its 600 V 12 A Qspeed diode, delivering the industry’s lowest reverse recovery charge (Qrr) for a silicon diode.
In general, the term short circuit is commonly used to refer to a situation whereby a live or ‘hot’ wire carrying a current comes into contact with a neutral wire. This article explains the several types, causes, and consequences of short circuits in power electronics.
TDK Corporation extended its range of TVS (transient voltage suppression) diodes characterized by their extremely low capacitance values for bidirectional overvoltage protection to include the ULC series (Ultra Low Clamping & Capacitance). The SD01005SL-ULC101 type has a minimum capacitance of ~0.5 pF and the SD0201SL-ULC101 type of ~0.6 pF, both at 1 MHz.
