This research presents a three-port DC-DC converter for connecting a Li-ion battery and an ultracapacitor to the drive system of an electric vehicle (EV). The suggested converter handles pulse currents in an EV drive train by utilizing an ultracapacitor and steady state current with a battery. The ultracapacitor and DC bus ports can transmit power in both directions, allowing the ultracapacitor to supply and absorb peak currents during acceleration and braking.
