Usage Example

Dual-active-bridge converter with LLG-SPICE magnetics

A 50 V to 70 V, 150 kHz DAB (TI TIDA-010954 board) with a planar ER64 2:2 transformer and an ELP38 series inductor. Both cores are Landau-Lifshitz-Gilbert models with (θ, α) extracted from the MagNet neural networks. Change the operating point, then simulate.
