World's most precise AC loss calculation in Discontinuous Conduction Mode

Würth Elektronik eiSos upgrades the RED EXPERT online design tool

With RED EXPERT from Würth Elektronik eiSos developers can simulate the power inductors from Würth Elektronik.

The losses determined with RED EXPERT are based on current and voltage waveforms typical in applications. Besides the core and winding losses, they also include the losses arising from the specific geometries of the inductance, such as the air gap.

With this upgrade the losses for buck and boost converters in discontinuous conduction mode can be accurately determined. Registered users even get the different losses of all the inductors clearly presented.

On top, this upgrade contains a new loss feature which has been added to calculate losses of any inductor irrespective of converter topology.

This AC loss model works very accurate for duty cycles from 0.1 to 0.9 and switching frequencies from 10 kHz to 10 MHz. The special feature: RED EXPERT enables the world's most precise loss calculation, with sinusoidal excitation, but rather is derived and validated from measurements of the power inductors in a switching controller set-up.

RED EXPERT is freely available in German, English, Spanish, Japanese, Russian and Chinese at www.we-online.com/redexpert.
