EE Core Based Drive Transformers
EE Core Based Drive Transformers are ideal for high frequency power converters, when an electrical pulse has to be transferred from the control stage to the power stage.
Sirio's EE Core Based Drive Transformers
Pulse transformers are used in high frequency power converters, when an electrical pulse has to be transferred from the control stage to the power stage, by keeping the galvanic isolation between the circuits, according to the required safety standards. The electrical signal is applied to the primary winding and transferred to the secondary side, to fire electronic switches. The 109, 117 and 118 families are based on different sizes of EE cores.
The part numbers listed below are some examples, Sirio can also develop special drive transformers with any turns ratio, dedicated and bespoke to your application.
