In power electronics, precision and thermal management decide the success of your design. With LiWiCalc®, a simulation environment in cooperation with Fraunhofer IISB, you calculate AC power losses and current densities of our PACK HF litz wires in real time. Optimize your windings on the basis of scientifically secured data and secure highest power density at minimal costs.
LiWiCalc® combines decades of practical experience with the latest findings from research. It is the fastest and most precise software for calculating dominant power losses on realistic litz wire geometries.
What distinguishes LiWiCalc®:
Highly realistic models: Use of an innovative Voronoi-based twisting structure for circular or square cross-sections.
High fill factors: Calculation of geometries with copper fill factors of more than 50%.
Scientific basis: Based on models published in specialist journals and scientifically validated.
Instructions for use
Define parameters: Enter your specific operating parameters (frequency, current, environment).
Select litz wire type: Choose the appropriate configuration from a database of available PACK HF litz wires.
Start simulation: Get immediate results on AC losses and thermal behavior.
Please note: This is a limited demo version:
The number of litz wires is limited to 300 on 2 geometry levels. The model size is limited to a wire length of 50 mm.
Tip: More precision - The expert advantages of the full version
The full version of LiWiCalc® makes your planning more precise through additional expert parameters. You map real conditions exactly by freely defining magnetic fields and frequency ranges. Use the full potential of our Fraunhofer cooperation for your measurable advantage.
