How To Choose Magnetic Core Size

converter power and circuit type (topology) versus core sizes and gives some useful thermal resistance values for ferrites. Manufacturers give rules of thumb of 5 W to 15 W of conversion power per cm3 for most core shapes (and 30 W/cm3 for toroids). This can be used in a computer program for choosing a core, though it is somewhat crude.

Permanent Magnet Generators | How it works, Application

Permanent magnet generators offer several advantages over traditional generators.
