Standby mode power innovations are a dream come true for designers looking to satisfy ever tightening power regulations. By Mike Richardson.

The drive to enable energy efficient power systems means standby power performance has become an important new consumer product design constraint.
As power saving policies and regulations continue to tighten in the drive to satisfy growing demands for global energy saving, manufacturers constantly have to dream up new smaller form factor designs that improve efficiency without increasing the cost.
In fact, it’s a continual battle; every manufacturer is trying to push product performance, enabling the customer to remove cost and make the required design changes needed to improve efficiency.
This comes as a result of regulations and standards that run around the basic tenet that it costs a great deal of money to not only to build new power generating facilities, but also to deliver this power to users once it is generated.
Energy Star, a voluntary US driven initiative set up by the Environmental Protection Agency and the Department of Energy, helps save money and protect the environment through energy efficient products and practices. By looking at the best performing power supplies in a particular market sector, Energy Star strives to ensure all manufacturers adopt best practice within the industry. And as the standards become more cognisant of the actual equipment operating conditions, there is a growing interest in ensuring that they reflect ‘real’ usage. This makes it harder for the power supply manufacturers that are having nightmares in trying to keep apace with their customers’ strict energy efficiency guidelines.
