Triad Magnetics DGE25-1 Gate Drive Transformer

Description:

The Triad Magnetics DGE25-1 Gate Drive Transformer is used in high-frequency switching power supply circuits to provide electrical isolation between control circuitry and power switching devices. Commonly installed in switch-mode power supplies (SMPS), DC-DC converters, motor drives, inverters, and industrial power electronics operating at frequencies above 200 kHz. Maintenance teams, power electronics engineers, and OEM manufacturers use this transformer for equipment repair, power supply replacement, new circuit designs, and industrial control system integration.

Applications:

The Triad Magnetics DGE25-1 gate drive transformer is commonly used in industrial automation, variable frequency drives (VFDs), UPS systems, renewable energy inverters, welding equipment, and high-frequency power conversion systems where galvanic isolation and efficient gate drive signal transfer are essential. Its interleaved winding construction minimizes leakage inductance for reliable high-speed switching performance.
