The 'world's most' precise loss calculation
With RED EXPERT, Würth Elektronik eiSos has published an online tool which developers can simulate the power inductors from Würth Elektronik. With just a few clicks, the power inductors are selected and the complete AC losses calculated. The special feature: RED EXPERT enables the 'world's most' precise loss calculation, because it is not based on the known Steinmetz models with sinusoidal excitation, but rather is derived and validated from measurements of the power inductors in a switching controller set-up.
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 50kHz to 5MHz. This gives the RED EXPERT AC loss model a previously unattained precision.
