Designing the PCB Thermal Path for Power MOSFETs
Turn package loss into a realistic junction-temperature estimate by designing and validating copper spreading, vias, interfaces, and airflow together.

Why MOSFET Coss Matters in an LLC Resonant Converter
Use output charge and effective capacitance—not one small-signal Coss value—to assess dead time and zero-voltage switching in an LLC stage.

Single-Pulse vs Repetitive Avalanche: What MOSFET Ratings Mean
Why a MOSFET that survives one unclamped inductive event may still need substantial derating for repetitive avalanche operation.

Optimizing Dead Time in Synchronous Rectification
Reduce body-diode loss without creating reverse current or shoot-through by tuning synchronous-rectifier timing across the full operating range.
