As the automotive industry continues its rapid shift toward electric mobility and high-efficiency power conversion, PREMO introduces the GDAU series — a high-performance lineup of Gate-Drive Transformers designed to meet the stringent requirements of today’s automotive and industrial power electronics.

⚙️ What Are Gate-Drive Transformers?

Gate-drive transformers play a crucial role in high-frequency switching systems by transferring control signals from low-voltage circuits to high-voltage transistors such as MOSFETs, IGBTs, and thyristors. These components provide galvanic isolation between the control and power stages, enabling:

• Reliable, noise-free switching
• Electrical safety
• Compact, high-speed operation

They are widely used in:

• DC-DC converters
• EV/PHV inverters
• Power factor correction (PFC) stages
• Motor drives
• Battery management systems (BMS)

🚗 Introducing the GDAU Series by PREMO

The GDAU series has been engineered specifically for high-efficiency, space-constrained automotive environments, offering high reliability across a wide temperature range and supporting various topologies including forward, push-pull, and thyristor control.
