This paper focuses on the possible hazards, the required auxiliary components and safety requirements for the DC bus of an electric vehicle (EV). High DC bus voltages are very attractive for keeping the current low and making light weight electronics. It is also recommended that car passengers are not exposed to high magnetic fields, this is also in favor for the use of high DC bus voltages. However, if the DC bus voltage exceeds 75 VDC additional safety measures are required in order to avoid electrocution of car users and maintenance personnel. Moreover ripple current on the DC bus may not cause electromagnetic interference (EMI) failures and thus must provide failure free car operation. Furthermore hazards can also be initiated by a car accident and affect the DC bus, e.g. a fire caused after DC bus short circuit. A DC bus concept with auxiliary components is proposed that includes an insulation monitoring safety device. Experimental results are also presented for the simulation of insulation faults on an EV test bench.
