Welding transformer output power

welding transformer simulation, transformer volt ampere characteristic, electric circuit analysis

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.

Results:

R, Ohm	U, V	I, A
infinity	100	0
20	95.6	4.78
10	88	8.8
5	70.7	14.14
2	38.8	19.4
1	21	21
0	0	21.9
