Abstract

In recent electronic vehicles (EVs) and hybrid vehicles (HVs), there are growing concerns about electromagnetic interference (EMI) caused by significantly-high voltage switching in DC-DC converters. The most remarkable characteristic of the coverter noise is in its periodicity. In this article, a noise injection experiment to a controller area network (CAN) bus by using a DC-DC converter is presented. Dispite the switching period of the converter was much shorter than the time length of a data frame transmission, we found that the switching did not always cause CAN errors. On the basis of this observation, we discuss characteristics of the converter noise and some basic ideas for improving the immunity of CAN networks against the converter noise by using dependable computing techniques.
