High frequency magnetic devices for solar inverters

Are high-frequency standard magnetic links suitable for medium-voltage power converters?

The high-frequency standard magnetic links were recently considered viable candidates for construction of the medium-voltage power converters, rather than link with the common dc specialized magnetic materials, like nano-crystalline and the amorphous materials.

Are magnetic materials suitable for MHz Power Conversion?

To achieve this miniaturization, designers of inductors and transformers need magnetic materials with good properties in the MHz regime. In this paper, we argue that available materials are not optimized for MHz power conversion applications—even those that are marketed as such—and that further development of magnetic materials is needed.

What is an example of a magnetic converter?

Examples of converters with magnetics belonging to the “ac case” include discontinuous- and boundary-conduction-mode converters, pulse-width-modulated isolated converters, the dual active bridge converter, resonant converters, resonant switched-capacitor converters, etc.

Why do power converters need magnetic materials?

Power converters are increasingly being operated at switching frequencies beyond 1 MHz to reduce energy storage requirements and passive component size. To achieve this miniaturization, designers of inductors and transformers need magnetic materials with good properties in the MHz regime.
