RED EXPERT Online Design Tool for Precise AC Loss Calculation

Würth Elektronik recently published RED EXPERT,  a new online tool you can use to simulate the power inductors. With just a few clicks, you can select the power inductors and calculate the complete AC losses.Wurth-RedExpert

RED EXPERT enables extremely precise loss calculation because it is not based on the known Steinmetz models with sinusoidal excitation. Instead, it is derived and validated from measurements of the power inductors in a switching controller setup.

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.

Particular highlights of the RED EXPERT AC loss model are the range of duty cycles supported from 10% to 90% and the switching frequency range of 50 kHz to 5 MHz. This gives the RED EXPERT AC loss model a previously unattained precision.

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