welding transformer simulation, transformer volt ampere characteristic, electric circuit analysis
This is an example of the welding transformer simulation, performed with QuickField software.
Plane-parallel problem of AC magnetics.
C = 1 μF, R = 0..10 Ohm;
Primary voltage V = 220 V;
Frequency f = 60 Hz;
Primary number of turns = 1200;
Secondary number of turns = 220;
Calculate the output U(I) chart of the welding transformer.
A series of problems with different R value were automatically generated and simulated using LabelMover parametric tool.
Magnetic flux density distribution and the electric current for the R=0.1 Ohm.
Output characteristic of the welding transformer:
