With RED EXPERT, Würth Elektronik eiSos has published a new online tool with 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. 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.
