| Abstract: | There was noise problem with its capacitance when traction converter employed on a certain EMUs was being rebuilt. The paper studies the problem. By analyzing its electric circuit, the paper simulates and makes a thorough study of resonance phenomenon and its rule, mechanism of noise generation and methods of reducing noise when capacitances connected in parallel. In the last, the solution to the problem is put forward. |
