Switchmode/High Frequency Gate Drive Transformers GDE25-4 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.
