Primary inductance and clamp
Type Vin_min, Dmax, Pin, fsw, and Krf. Every number is the printed formula. No ferrite core catalog.
Worked example
Lp 0.001265625 H
Lp=Vin_min^2*Dmax^2/(2*Pin*fsw*Krf)
Empty boxes are not zero. K and Kcrit appear only when D, Lp, fsw, Rload, Ns, and Np are nonzero. lg uses the typed Lp, Np, and Ae. A 47 kOhm wireframe value is not used.
Worked examples
- Example Vin_min 100Lp uses 100, 0.45, 20, 100000, and 0.4. Other boxes stay empty.
- Example DCM boundaryK uses the typed Lp. CCM and DCM follow the strict comparison only.
- Example clamp and gapVclamp, snubber, and lg use the typed numbers. Ae is not looked up.
