Planar vs. wire-wound transformers: a quantifiable engineering selection guide
Planar and wire-wound transformers are not substitutes — they fit different constraints. This article breaks the selection boundary into six quantifiable criteria (height 22–28 vs 8–14 mm, high-frequency AC winding loss, leakage 3%–8% vs 0.5%–2%, thermal path, batch consistency ±10~15% vs ±3~5%, overall cost) and gives the judgement order "height → frequency → cost" plus how to handle the 100–500 kHz overlap zone.

SST Live Hot-Swap: The Scalability Switch Hiding on the Last Line of the Spec Sheet
Beyond efficiency, power density and availability, what decides whether the solid-state transformer (SST) scales commercially is live hot-swap. This article breaks down the four hard constraints that keep the medium-voltage side from live hot-swap, quantifies MTTR's impact on five-nines availability, and surveys vendor module-replacement capability in 2026.
