This is an example of the welding transformer simulation, performed with QuickField software.
Plane problem of AC magnetics.
R1 = 1000 Ohm;
C1 = 1 nF;
Frequency f = 60 Hz;
Number of turns = 220;
Calculate the output U(I) chart of the welding transformer.
A series of problems with different R1 value were automatically generated and simulated using LabelMover parametric tool.
Output characteristic of the welding transformer:
