A Holistic Approach Can Pave The Way To Greater Power Efficiencies
This article by Sagentia's David Stocks and Paul Roberts featured in Electronic Design Europe talks about power-supply efficiency.
Engineers know that improvements in digital electronics and power electronics give us ever more efficient power supplies. Consumers know that energy efficiency is now an important consideration when choosing between products. For example, the market share for energy-efficient lighting in the U.K. is expected to grow from 36% of the overall lighting market in 2009 to 63% by 2014.
Power-supply efficiency is therefore key to a well-designed product, but it’s not the only factor. Overall system efficiency is also very important. It’s typically the function of a complex tradeoff between a number of variables including power loss in various parts of the system under diverse operating conditions, system performance, cost, size, and even speed to market.
Improvements in digital electronics, particularly the trend toward tighter integration of more sophisticated peripherals such as analogue-to-digital converters (ADCs) and pulse-width modulation (PWM) in microcontrollers, can improve power efficiency and open up new product opportunities.
