Transformers

Würth Elektronik Transformers feature power transformers for AC/DC, DC/DC, data/signal, battery management systems (BMS), and interfaces. Additional transformer solutions are gate drive and current sense transformers. These Würth power transformers feature several topologies, including flyback, push-pull, isolated buck, forward, and half-bridge. Würth Elektronik transformers are ideal for power electronics, LED lighting, signal applications, white goods, and more.
