Switchers won't compromise on efficiency

A power supply without compromise is every designer's dream, and Lambda reckons its new NV-Power range turns that dream into reality.

A power supply without compromise is every designer's dream, and Lambda reckons its new NV-Power range turns that dream into reality.

Pushing back the barriers, the company describes NV-Power as a new range of class leading high density and environmentally friendly AC/DC power supplies that gives designers their no compromise power solution.

"Limited levels of efficiency have always meant that AC/DC power supplies come with tradeoffs", explains Martin Southam, Lambda Europe Marketing Director.

"Certain aspects have always had to be compromised, be it output power, size, minimum load, noise, or EMC performance.

In NV-Power we have an AC/DC power supply technology that cuts switching losses by 50% to deliver an unparalleled efficiency of up to 90%.

It is this massive leap forward in efficiency that has enabled us to create a range of power supplies that do not compromise any of the fundamentals".

NV-Power is based around a configurable planar transformer, and employs multiple efficiency gain (MEG) technology to achieve its class leading efficiency for multiple-output PSUs.

The Lambda approach is essentially a unique use of synchronous rectifiers in a resonant topology.
