| Abstract: | It is difficult for fuel cell with weak output characteristic to match with motor driver, adopting DC/DC converter to improve its output characteristic is necessary, the converter is in complex electromagnetic environment and affected by many interference factors, so, the key of assembly and reliable operation is the design of electromagnetic compatibility well. In this paper, the electromagnetic environment and electromagnetic interference factors affecting DC/DC converter used for electric vehicle fuel cell in step-down main circuit were analyzed, the main antijamming design measures for above factors were discussed also. |
