In a course on industrial electronics, a graduate level course, taught by Dr. Joseph A. Boyd, we were assigned the problem to hand sketch the transient change of flux (or flux density if you wish) as a function of time for the above 1/2 wave rectifier circuit with an assumed 0 residual flux density at the time of switch closure on a voltage zero crossing of a sine wave source voltage, and for several cycles after the switch closure. I got it approximately but not totally correct.
If I ever had to do that in a lab, I have long since forgotten.
I am using the free, 2D version of MagNet FEA software...you could easily simulate it here by...
Thanks. I may give it a shot. I've seen some other software to model transformers for supply design but I never took the time to investigate the limits of the models.
