World‘s most accurate AC loss model
Inductor losses are one of the critical factors in the design of an efficient power supply. In REDEXPERT you can determine accurately your total AC losses at any operating condition, with our world’s most accurate AC loss model for Power Inductors, which incorporate the AC core and AC wire losses.
Model based on actual components
- All types of core materials
- All core shapes (not only ring cores)
- Air gap and fringing effects
- Effects and changes in winding structure
Point of operation
The Model was measured with a pulsating square wave voltage, which is applied across the inductor and results in a triangular current with DC offset.
Compared to Steinmetz (blue), the Würth Elektronik (red) model has a higher accuracy over a wider range of duty cycles.
