Core Loss · Leakage Inductance · Insulation Stress
Overview
Transformer simulation addresses core loss, leakage inductance, winding proximity effects, insulation stress, and thermal hotspots — enabling optimised designs for power distribution, isolation, and high-frequency switching transformers. Accurate 3D electromagnetic FEA captures the winding field distribution and frequency-dependent AC resistance that analytical models cannot predict, while coupled thermal analysis identifies hot spots that limit continuous power rating and cooling requirements.
