Here are the results. LTspice has the additional benefit that I can easily study the effect of different design parameters (e.g. airgap size) on the saturation behavior by stepping parameters. In this screencap I am observing the primary current behavior when going into saturation with airgap of...
Yes there are different levels of nonlinear models available in LTspice. There is the example 32 NonLinearTransformer.asc shipped with LTspice using the CHAN model. I was hoping that solving the actual nonlinear problem even only with numerical methods could give more insight or at least teach...
What are the possible ways of solving the operating point of air gapped transformer with nonlinear B-H curve? For example let's consider 3C90 E34 sized core with 0.5 mm airgap. I know that the magnetomotive force over the ferrite part can be formulated as function of the reluctances...
Actually there would be no asymptotical approaching because for ideal inductor the phase angle would always be 90deg and for real inductors the phase angle would still not be assymptotically approaching anything. The phase angle for impedance is tan^-1(imaginary part/real part) so the only thing...
If you connect impedances Z1 and Z2 in series the resulting impedance is Z = Z1+Z2. I guess you propably knew that so the reason why zoki tried to guide you in the direction of phasors is the fact that when you add imaginary numbers together it doesn't affect the phase angle. Multiplication does...
