An EFD17-class transformer can fit a height-constrained auxiliary power board, but matching the core family does not make two parts interchangeable. In a multi-output flyback transformer, pin mapping also controls…
In an LLC resonant converter, magnetizing inductance Lm and resonant inductance Lr may both be implemented in one high-frequency transformer, but they do different jobs. Treating open-circuit primary inductance,…
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.
