  Rapid charger is getting more and more important as the electric vehicle (EV)
getting popular. The rapid charging technique plays an important part in the
electric vehicle development. Multiport converter is used in the rapid charging
technique to reduce the required current and also provides some other
advantages. In this paper, the literature review form multiport converter to
the rapid charger of electric vehicle is introduced. Some topologies of
multiport converter are discussed in the literature review. Triple active
bridge topology (TAB) is selected as it is useful and commonly used. The
feasibility of using Sinusoidal Pulse Width Modulation (SPWM) to control the
converter is also discussed in the simulation part. A simple hardware design
and experiment is included at the end.
