Abstract
Buck-boost converter is an important component of electric automobile, it is an important interference source in electric automobile, the study of the interference source is very important to restrain interference. The buck-boost converter in continuous conduction mode (CCM) is established by using circuit simulation software PSPICE. According to the request of GB18655-2002, the simulation study on common-mode conducted interference,differential-mode conducted interference and far-field radiated interference of buck-boost converter are given. The common-mode current radiation of buck-boost converter is simplified as an electric dipole radiation mode and the differential-mode current radiation is simplified as a rectangular loop antenna. In order to improve the electromagnetic compatibility of buck-boost converter in electric automobile, some measures to reduce the conducted interference and the radiated interference are proposed.
