Simple tools for MOSFET driver selection

Posted on 01 December 2008

      Select the correct power-switching element for the application A simple spreadsheet, and a few equations, could hold the key to selecting the optimum MOSFET driver for each application. By Cliff Ellison, Microchip Technology Inc.   Charging and discharging a MOSFET’s gate requires the same amount of energy, regardless of how fast or [...]

Watching Out for You

Posted on 01 December 2008

      Continuous monitoring is important in backup battery applications We increasingly rely on technology to provide us with a feeling of security; cameras, emergency telephones and even safety lighting have a reassuringly high profile, letting us know that, if they are ever needed, they’re available. Ensuring their availability in times of emergency can [...]

Power Semiconductors Take the Lead for Pulse Power Applications

Posted on 01 December 2008

      Solid State Switches from ABB for pulse power applications Pulse power applications have for long been dominated by electron tubes like thyratrons and ignitrons. Due to the increased performance, the controllability and the long life time of power semiconductor devices, the tubes are gradually being replaced by power semiconductor assemblies The improved [...]

Capacitor Advances for Leaner, Faster, Power Distribution

Posted on 01 December 2008

      Designers can replace conventional capacitors Power distribution networks for PC processors are slimming down to respond more quickly to large changes in current demand at low operating voltages. High-speed voltage regulator modules and new capacitor technologies optimised for very low equivalent series inductance allow engineers to reduce size and component count by [...]

Power Management Device for Door Zone Systems

Posted on 01 December 2008

      Battery life is the most important factor in electronic modules for automotive Vehicle manufacturers call for lower and lower current consumption for every module in the car: severe requirements are common to almost all the ‘over key’ applications in the body segment. Those specific electronic subsystems must also operate in ultra-standby mode, [...]

Time Controlled Power-Save Mode

Posted on 01 December 2008

      More Flexibility For Low-Power Synchronous Buck Converters Modern synchronous buck converters for portable applications provide so called power-save mode operation to maintain high efficiency over the entire load range. At light loads, the converter operates with pulse frequency modulation (PFM mode) and provides automatic transition into pulse width modulation (PWM mode) at [...]

Integrating PID Controllers into Automated Processes via Ethernet

Posted on 01 December 2008

      Ethernet will play a significant role in the foreseeable future Ethernet communications is rapidly gaining popularity in industrial applications because it enables the real-time exchange of information between processing equipment and companies’ Ethernet-based management systems. By Sean Wilkinson, Watlow   Ethernet technology is becoming widely accepted due to multiple factors, including: • [...]
