Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal ...

Relationship of power density and field strength. Some of the more uncommon power-density apps. RF designers frequently need to know the true power density or field intensity at a particular distance ...

A stacked DBC packaging method utilizes mutual inductance cancellation effects to significantly reduce parasitic inductance. With the current path increased by one-fold, SiC power modules allow for ...

Researchers at Shanghai Jiao Tong University in China have designed a new sodium-sulfur battery ...

Scientists at Lawrence Berkeley National Laboratory and UC Berkeley have created what they're calling "microcapacitors," which integrate energy storage directly into the microchip itself, solving the ...

Berkeley Lab scientists create microcapacitors with ultrahigh energy and power density. The microcapacitors are made with engineered thin films of hafnium oxide and zirconium oxide. The technology ...

onsemi has developed power semiconductors based on a vertical GaN (vGaN) architecture that improves efficiency, power density, and ruggedness. These GaN-on-GaN devices conduct current vertically ...

Amprius is working on ensuring that its wearable battery fits into military operations. The battery will be part of a new Amprius battery vest, which will use batteries with silicone anodes to give ...
