High-Frequency Cores for Chokes and Power Transformers

VACUUMSCHMELZE (VAC) is exhibiting first cores and common mode chokes made of the nanocrystalline material VITROPERM® 550 HF at PCIM. The newly developed alloy enables next-generation components with optimized size and weight.

The constant demand for smaller and lighter systems is also a challenge in power electronics. With the material innovation VITROPERM 550 HF low-cost cores, chokes or power transformers in compact design for demanding requirements can be realized.

The components show significantly improved high-frequency behavior compared to solutions made of VITROPERM 500 F or typical EMC ferrites.

Applications for the high-performance materials are e.g. switched mode power supplies, wind or solar inverters and frequency converters. In the automotive sector, common mode chokes in the drive train offer enormous advantages in size - components that are up to 60% smaller can be produced cost-effectively.

Furthermore, power transformers with significantly reduced core losses can be realized for the use in wall boxes or in on-board charging systems for charging electric vehicles.

VAC will be exhibiting at PCIM in Hall 7, Stand 7-123 from June 5 to 7.
