Welding transformer output power

This is an example of the welding transformer simulation, performed with QuickField software.

Problem Type:
Plane problem of AC magnetics.

Geometry:

Given:
R1 = 1000 Ohm;
C1 = 1 nF;
Frequency f = 60 Hz;
Number of turns = 220;

Problem:
Calculate the output U(I) chart of the welding transformer.

Solution:
A series of problems with different R1 value were automaticaly generated and simulated using LabelMover parametric tool.

Results:
Output characteristic of the welding transformer:
