Heterogeneous Integration: A Promising Technology to Future Integrated Power Conversion Electronics
Since its renaissance, heterogeneous integration (HI) where unique merits of different silicon or III-V technologies, has been widely explored in many power electronics and achieved remark- able success. It is known that the success of power conversion electronics is mostly attributed to the low-power, fast-response, and accurate mixed-signal control circuitry and the low-loss, … [Read more...] about Heterogeneous Integration: A Promising Technology to Future Integrated Power Conversion Electronics
Reliability of Silicon Battery Technology and Power Electronics Based Energy Conversion
Continuous improvements in battery technology has paved the way for adoption in growing number of applications. However, the state-of-the-art graphite anodes remain sensitive to heat dissipation during fast charging or short circuits, and possibly causing inflammation of the battery. This is a limitation for safety critical applications and prevents ultra-high charging rates. … [Read more...] about Reliability of Silicon Battery Technology and Power Electronics Based Energy Conversion
