High-Speed Gate Drive Transformer | 1:1 / 1:2 Winding Ratio
Product Overview High-performance Gate Drive Transformers engineered to provide reliable galvanic isolation and deliver high-peak-current driving signals to the gates of power MOSFETs and IGBTs. Designed with a small number of turns (5–30 turns) to minimize leakage inductance and ensure ultra-fast switching speeds. Available in standard 1:1 or 1:2 primary-to-secondary ratios, making them highly versatile for modern high-frequency power switching applications.
