Würth Elektronik eiSos upgrades online design tool

April 7, 2016

Waldenburg, Germany. Würth Elektronik eiSos announced that it has upgraded RED EXPERT, with which developers can simulate 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 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 is accurate for duty cycles from 0.1 to 0.9 and switching frequencies from 10 kHz to 10 MHz. RED EXPERT enables precise loss calculation, with sinusoidal excitation and derived and validated from measurements of the power inductors in a switching controller set-up.

RED EXPERT is free and available in German, English, Spanish, Japanese, Russian, and Chinese.
