Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.

A Word to the Wise: Know Your Power
Power related issues are a growing predicament on a global scale. The global population and industrial development are growing more rapidly than existing power infrastructure can handle, having a detrimental effect on efficiencies worldwide. The ever increasing global power issues all stem from an international power grid that is, in a word, archaic.

Power Device Consideration for Optimized Design of LED Power Supply
Switch-mode power supplies for LED lighting applications are increasingly being designed with an active power factor correction (PFC) at the input stage to meet international regulations for harmonics. The boost topology in discontinuous current mode (DCM) is most suitable PFC method for converters less than 300W power rating. In this topology, the switching-on power loss of boost switch is negligible, and the major power losses are the switching-off losses and conduction losses. After the super-junction devices have been introduced, they are often considered as an optimized switch for active PFC because of extremely low on-resistance and highly non-linear capacitance curves. For downstream converter, LLC resonant converters are proven to be very effective for higher efficiency.

The Nation's Quest for Energy Efficiency and Renewable Energy Adoptions in Net Zero Energy Buildings
The nation’s quest for Net Zero Energy Buildings is likely to change a great deal about the way we approach designing and constructing buildings in the future. From the use of a broadened integration team in early planning and the heightened use of BIM tools, to the consideration of a diverse pallet of energy efficient building solutions and site-based power generation and storage, the days of incremental improvement of older technologies may not meet the challenge.
