nWave is Lineage Power branded technology for using digital signal control techniques in power supplies. Replacing analog hardware in power supplies with nWave technology provides significant immediate benefits in terms of cost, size, density, and performance, and also opens the door to long-term benefits such as feature enhancements and rapid customization that are either impractical or impossible with analog technology.

DALLAS – (Nov. 11, 2005) -- Tyco Electronics Power Systems, Inc. today announced its new breakthrough nWave technology for digital power. The new technology is based on Tyco Electronics’ extensive knowledge and experience in digital power, and represents the latest advances in the use of DSPs (Digital Signal Processors) in power supplies. Power supplies utilizing this technology provide customers with benefits such as improved efficiency, reliability, density and control.

As systems get smaller and denser, heat management becomes a greater concern, prompting the need for greater efficiency. More efficient rectifiers are desired not only because of lower energy cost, but also because they enable increased density. Efficiency is also important for N+N and N+1 redundant systems where power converters are not running at full load. With the use of digital control techniques, it is possible to alter switching/control parameters to maximize efficiency for all load conditions.

One of the many benefits from using the nWave technology includes the ability to shorten time-to-market by allowing for software, as opposed to hardware, changes during the development cycle. Furthermore, rectifiers with digital control technology can be easily customized through programming to meet particular customer needs, as compared to costly hardware modifications.

“We are fully committed to our nWave technology because it allows for more value-added features, improves reliability and reduces cost,” says Sabi Varma, vice president, marketing and R&D at Tyco Electronics Power Systems, Inc. “The potential of digital-control to bring new value-added features to our customers is unlimited.”

nWave technology can reduce parts count, allowing for smaller rectifier packages with increased power density. It can also replace many of the functions that are performed by analog means today, including PWM loop control, loop compensation, current sharing, current or power limiting, and external communications and their associated circuitry. In addition, the nWave technology may be used to provide digital information through communication busses such as PMBus/SMBus without the need for a separate microprocessor.

“The use of nWave for full-control of the power supply will bring even more creative product features, without additional cost, as the technique evolves,” says David Rosenbluth, director, research & development at Tyco Electronics Power Systems, Inc. “This technology will be integral in our future product releases.”
