Deep technical guides for engineers working across converters, semiconductor devices, solid-state transformers and wireless power.
Tutorials on established engineering are being reviewed one by one for AIPE Academy and stay at their current addresses. Open research questions live in Frontiers; product updates in News.

Topology, modelling, magnetics, control and simulation for practical power converters.
Why resonance beats hard switching — the LLC tank, FHA gain curves, ZVS, the capacitive region to avoid, and how to design and simulate one.
