Isolated phase bus (IPB) is generally used in power plants to connect the generator to the main transformers due to its shielding ability. And this paper presents the electromagnetic shielding effectiveness analysis of the IPB applied in International Thermonuclear Experimental Reactor poloidal field converters. The circulating currents induced in the enclosures and the magnetic field around the IPB are analyzed and studied. An equivalent electrical circuit is built to analyze the circulating current with a nonsinusoidal input by solving the corresponding numerical differential equations. And an experimental test is also performed on a full scale prototype to verify the model and results of the analysis. In addition, magnetic field distribution around the IPB is analyzed based on the Fourier decomposition and finite-element method. The analysis result indicates that the IPB is of good electromagnetic shielding ability. And the method of the analysis presented in this paper is proved to have great value in the analysis and design of IPB used in converter systems.Index Terms-Circulating current, electromagnetic shielding effectiveness, International Thermonuclear Experimental Reactor (ITER) poloidal field (PF) converter, isolated phase bus (IPB), magnetic field distribution.
