In the rectifier, the overheating of the structure of the rectifier occurs under the influence of a magnetic field caused by high current. It is difficult to carry out an experiment for high current by using a real rectifier, because of facilities and costs. Therefore, it is very useful to apply magnetic field analysis to examine the overheating of the structure of the rectifier by JMAG. However, there were problems to modeling and the great calculation time by the many parts , the complexity of the parts shape of rectifier. In this lecture, we report the result of improvement of analysis precision, the case study method for outline or materials decision of rectifier under the magnetic field analysis of the rectifier by JMAG.
