PREMO Unveils GDAU Series: Advanced Gate-Drive Transformers for EV and Power Electronics
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.
