Gearing Up For Next-Gen Power Semis


After years in R&D, several vendors are moving closer to shipping power semiconductors and other products based on next-generation wide-bandgap technologies. These devices leverage the properties of new materials, such as aluminum nitride, diamond, and gallium oxide, and they are also utilized in different structures, such as vertical gallium-nitride power devices. But while many of thes... » read more

Chip Shortages Grow For Mature Nodes


The current wave of chip shortages is expected to last for the foreseeable future, particularly for a growing list of critical devices produced in mature process nodes. Chips manufactured at mature nodes typically fall under the radar, but they are used in nearly every electronic device, including appliances, cars, computers, displays, industrial equipment, smartphones, and TVs. Many of thes... » read more

A Revolution For Power Conversion Systems — CoolSiC MOSFET


Silicon carbide (SiC) transistors are increasingly used in power converters, placing high demands on the size, weight and/or efficiency. The outstanding material properties of SiC enable the design of fastswitching unipolar devices as opposed to bipolar IGBT devices. Thus, solutions which have been up to now possible in the low-voltage world only (< 600 V) are now possible at higher voltages... » read more

System-Level Electro-Thermal Analysis of RDS(ON) for Power MOSFET


Authors: Rajen Murugan1, Nathan Ai2, and C.T. Kao2 1 Texas Instruments, Inc., Dallas, Texas, 75044, USA 2 Cadence Design Systems, Santa Clara, California, USA A coupled-electro-thermal RDS(ON) (drain to source ON resistance) co-analysis methodology for Power MOSFET is proposed. The methodology contains two functional modules: 1) physical field solvers and 2) equivalent circuit/network so... » read more

Electric Cars Gain Traction, But Challenges Remain


Battery-powered electric vehicles are expected to reach a milestone in terms of shipments in 2019, but the technology faces several significant hurdles to gain wider adoption in the market. Limited driving range, high costs, battery issues, and a spotty charging infrastructure are the main challenges for battery electric vehicles (BEVs). In addition, there are issues with various power semic... » read more
