Features • Convert power-level voltages from one level or phase
confguration
• Converts voltage levels while maintaining the VA
• Excellent as isolation step-down and high voltage step-up transformers and autotransformers
• Closed ring shape eliminates air gaps inherent in the construction of an E-I core
• Primary and secondary coils can be wound concentrically to cover the entire surface of the core, providing screening to minimize the core’s magnetic feld from generating electromagnetic interference
• Ferrite toroidal cores are typically used at higher frequencies, between a few tens of kilohertz to hundreds of megahertz to reduce losses, physical size and weight of inductive components
• Other core types ofered (but not limited to: Iron Powder (higher permeability), MPP (for higher accuracy), 49% nickel (for low loss and low distortion) and 3% silicon steel alloy (over double the fux density of MPP)
Advantages Over Laminate E-I Type • Smaller size (about half )
• Lower weight (about half )
• Less mechanical hum (making them superior in audio amplifers)
• Lower exterior magnetic feld (about one-tenth)
• Low of-load losses (making them more efcient in standby circuits)
• Single-bolt mounting
• Light fxtures
• Robotics
• UPS
Applications • Avionics
• Medical electronics
• Motor controls
• Electric cars
• Industrial control panels
• Staging microphones
