GDE25-1_13 Datasheet, PDF (1/1 Pages) TRIAD MAGNETICS – Switchmode/High Frequency Gate Drive Transformers

Switchmode/High Frequency
Gate Drive Transformers
GDE25-1
Description:
Triad gate drive transformers are used universally in all high frequency switching
topologies to isolate the control circuitry from the line-connected switches. The
Windings are interleaved for the lowest possible leakage inductance. Turn ratios
optimize coupling and enhance performance. Available with single or dual
secondaries, these transformers are constructed of UL rated 130° materials and are
easily standardized at operating frequencies of 200 kHz and beyond.

Technical Notes:
1. Drive to gate winding hi-pot tested at 3,750 VRMS.
2. Derate ET product by 32% for 50 kHz, 50% for 100 kHz and for
unidirectional operation.
3. Operation at rated current per winding renders approximately 40°
temperature rise.
