The Technical Benefits of PrimePACK™ Modules in CAV Applications

Posted on 23 July 2020

      Module baseplate is a key design element for robustness and extended system lifetime The increase in energy consumption and crude oil demand over the last decade has created increasing pollution and global warming. Electrification of propulsion drives in vehicles improves the transmission efficiency and allows significant savings in fuel costs and CO2 [...]

Fiber Optics in Solar Energy Applications

Posted on 23 July 2020

      They offer insulation protection from high-voltage/current glitches Solar energy has recently become a popular alternative source to meet energy demands around the world due to the fluctuation of oil/coal prices and global warming issues. Oil is a limited and diminishing resource, and because of this, the price surges when demand is high. [...]

History of FET Technology and the Move to NexFET™

Posted on 23 July 2020

      The advantage comes from the low-input gate charge Introduced as a substitute for bipolar transistors, power MOSFETs were used as an electronic switch for power management applications. A power MOSFET has a high input impedance. This means it is a voltage-controlled, unlike the current-controlled, bipolar switch. In other words, a power MOSFET [...]

Optimizing Microcontroller Power Efficiency for Ultra Low Power Designs

Posted on 23 July 2020

      To preserve efficiency, the MCU needs to support multiple operating modes The rise of ultra low power applications has changed how developers must approach power optimization. Devices must support single-cell battery operation, charge/discharge closer to battery thresholds, and be able to control motors and/or high brightness LEDs, all while reducing device form [...]

A Truly Connected Mobile Experience

Posted on 23 July 2020

      The Push for USB OTG The beauty is to charge a battery per the latest USB Battery Charging Specs, using a high efficiency buck topology converter that utilizes a chip inductor for minimized space and cost, but can then run the buck controller in reverse as an effective boost controller requiring no [...]

Interview on High PowerTechnology with Sven Klaka, ABB Switzerland Ltd, Semiconductors

Posted on 23 July 2020

      By Bodo Arlt, Editor BPS   Bodo Arlt: What end markets will drive power technology at ABB Semiconductors? Sven Klaka: Our traditional markets are Traction, Industry (Medium Voltage Drives, Aluminium Smelting, Starters, Excitation Systems) and Power Transmission (HVDC and FACTS). On top of that we are seeing more and more semiconductors going [...]

Simple Light Load Mode Control Optimizes Power Efficiency

Posted on 23 May 2020

      The target is in Point-of-Load Switching Regulators Efficiency ratings for power supplies at full load do not adequately reflect the unit’s power consumption under actual operation conditions. Improved efficiency at all operating points including more typical situations such as very light loads is an important concern in the design of next generation [...]
