Package size and a 1:1 ratio are only screening filters when selecting an SMD gate drive transformer supplier. Reliable MOSFET, IGBT, or SiC gate drive depends on volt-second capability, magnetizing inductance, leakage…
Gate drive transformer values are comparable only when connection, frequency, signal level, and equivalent-circuit mode are the same. Common errors include testing with the wrong secondary condition, using a long…
A gate drive transformer can isolate and transfer gate-drive pulses, but it cannot hold a DC high level indefinitely like a digital isolator. The turns ratio is not the limit. The core must receive alternating positive…
Learn why a 1:1 gate drive transformer can still cause amplitude loss, pulse droop, slow edges, and ringing—and how to troubleshoot magnetics and the gate loop.
PoE power delivery grew from 15W (802.3af) to 90W (802.3bt) in 15 years. How each standard generation changed transformer core size, winding, saturation margin, and isolation requirements.
Transformer DCR is listed as "reference only" on most datasheets, but it quietly costs you 5-10% efficiency in high-current designs. When it matters, how to calculate the real cost, and how to spec it properly.
