Example Vin_min 100
Lp uses 100, 0.45, 20, 100000, and 0.4. Other boxes stay empty.
Worked example
Primary inductance 0.001265625 H
Use the Lp you type
Lp 0.001265625 H
Show equation
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. Gap length uses the selected Lp, Np, and Ae. High voltage is not a safety approval.
