Designing high-temp electronics for auto and other apps
High-temperature semiconductor technologies can survive temperatures approaching 400°C, but careful design of the product is required to deliver cost-effective devices achieving stable, predictable performance.
Multi-pronged approach reduces carbon dioxide emissions
In order to significantly reduce the CO2 emission of a car, it is not sufficient to attack at one single point. In contrast, it is necessary to use a combination of more efficient drives, electrification, assistance systems and maximum driver integration. Continental explains its integrated system approach to make engines and vehicles more economical.
Electronic Control for One-cylinder Engines
Anti-pollution legislation around the world affects in particular the design for small gasoline engines. In order to meet future requirements, mechanical engine control systems have to be replaced by electronic ones. Freescale has developed a reference design for this application.
Electric motor efficiency depends upon power factor - Part 2
Electric motor power efficiency has taken center stage. Individuals, corporations, and governments are increasingly interested in saving power, and we now have the technology that can make it possible. In this second part of a two-part series, Actel shows you how to improve your design's power efficiency using active power factor correction and other techniques.
Increasing Large Li-Ion Battery Pack Energy Delivery with Active Cell Balancing
A major factor preventing the optimal usage of lithium ion batteries is cell mismatch. But there are methods and ways to handle and even prevent this unpleasant condition. The article describes how.
Hybrid battery is 25 kilograms of pure energy
Developing an efficient battery management system
Delivering HVAC efficiency improvements
Using LIN-based mechatronic valve control to drive efficiency improvements in automotive climate control systems
Knock detection using wavelets
The authors describe a new engine knock detection approach based on a wavelet transform techniques. They conclude that a new adaptive knock detection approach is feasible using wavelet transform and that future work should focus on efficient hardware implementation.
