| description | The technology described herein discloses a non-isolated multiport dc-dc converter with three input dc ports to integrate three different energy sources namely fuel cell, battery and ultracapacitor, and two dedicated output ports for traction load and auxiliary loads, respectively. The invented system is capable of providing high flexibility in power flow management among the three energy sources, corresponding to diverse dynamic load power events encountered in an EV. Besides, the system exhibits prominent features like simultaneous and bidirectional power transferring capability between the multiple dc ports and single stage power processing in every possible power flow scenarios. Furthermore, the technology embodies distinct operating modes depending upon the dynamic load power variations and state of voltage levels of the energy sources. Nevertheless, the technology aims at improving the utilization efficiency of the energy storage system by maneuvering power flows between multiple dc ports, thereby augmenting the overall performance of EV powertrain. |
