From reluctance model:

so

and

so

Uniform Flux

assumed

slide16

(1)

(2)

slide18

core geometry (m5)

geometrical parameters

only

electrical and magnetic

parmaters

slide20

From Faraday’s Law:

From Ampere’s Law:

Assuming core with extremely steep

B-H loop

slide23

Intuitive argument:

Proportional

AREAPRODUCTAp

To fully utilize the core capability:

(1)

(square wave, V1 primary, V2 - second)

To fully utilize window area:

(2)

Substitution of (1) in (2) and rearranging

(3)

OR
