| High Light | Toroidal SMD gate drive transformer ，High frequency transformer with 4.5KVAC isolation ，SMD transformer for gate drive applications | ||
Engineered for precision control of IGBT/MOSFET power modules, our SMD Transformer series leverages toroidal core technology to deliver superior magnetic coupling and minimal EMI radiation. With reinforced isolation meeting 4.5KVAC Isolated Transformer standards (tested at 60 seconds), it ensures safe operation in industrial motor drives and 800V EV battery systems. The surface-mount design saves 50% PCB space while supporting 5W output power at 65kHz—enabling robust switching without compromising reliability.

Critical Note: Maintain ≥8mm PCB creepage distance for full isolation integrity.
Isolates low-voltage control circuits from 800V battery traction inverters.
Pair with: Current sensors for overcurrent protection.
Provides gate drive power for SiC MOSFETs in PLC-controlled servo systems.
Pair with: EMI filters to suppress 65kHz switching noise.
Enables duty-cycle adjustment (10%–50%) in solar microinverters.
Pair with: Power inductors for DC/DC auxiliary supplies.
Q: How does this differ from standard power transformers?
A: Designed specifically for Gate Drive Transformer applications:
Higher switching frequency (50–65kHz vs. 50/60Hz)
Lower leakage inductance (≤4μH vs. >100μH)
Reinforced isolation (4.5KVAC vs. 2.5KVAC typical)
Q: Can it eliminate shoot-through in half-bridge circuits?
A: Yes. The Toroidal SMD Transformer’s tight coupling (±1.1% ratio tolerance) minimizes propagation delay skew. Combine with dead-time controllers for optimal results.
Q: Custom turn ratios supported?
A: Standard ratios 1:1.25/1.4/1.5/1.71 (GT09-001 to 004). Contact for custom windings.
