IEC SC22E Strives for a General Switch-Mode Power Supply Standard

As the standardization landscape is ever-changing with new standards emerging and evolving, there is a great need to setup a new standard for switch-mode power supplies taking a state-of-the-art look at requirements, but with a view and sensitivity to the needs of the industry and the existing “legacy” products still in service.
Under a new lead, Hilmar Kraus and Holger Laible, the SC 22E standards body is now looking for additional initiatives related to new technologies that have been adopted by the power design engineering community.
During the last meeting of SC 22E held in Frankfurt in May 2012, new targets and measures were agreed and set. There was consensus between the participants to initiate the establishment of a modern up-to-date standard for switch mode power supplies.
New technologies and challenges like electric mobility, smart grid, wind energy and energy efficiency are rapidly developing. Additional intelligent building technologies are coming up requiring new types of power supplies. All these fields are encouraged by governments and the active promotion of “safe energy resources” in order to help prevent environmental pollution. Billions of existing power supplies, often operating inefficiently, which are installed worldwide have a huge impact on the environment and cleaning up this situation requires firm standards, greater awareness and government regulation.
Each industry develops its own product requirements. However, these industries are often using the older generation models of power supplies, often at a level of efficiency that unnecessarily consumes far too much power and in-turn, pollutes the atmosphere. SC 22E is convinced, that there is a significant benefit to the switch-mode power supply industry to harmonize these requirements for their products together with the introduction of new products and up-to-date technologies.

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.
