This paper presents a new power sharing algorithm for a hybrid power source of hydrogen fuel cells (HFC) and Li-ion battery cells (LiBC) based on state of charge (SOC) of the LiBC to supply a dual three-phase machine in light railways. HFCs are good energy sources to provide reliable power at a steady rate, while, LiBC have fast dynamics that can respond appropriately to the fast load transients. Double three phase permanent magnet synchronous machines (DTPMSM) have been nominated in this research since they provide high reliability in which the fault-tolerant operation can be implemented. Additionally, they provide lower power losses and harmonic distortion along with higher power density. Accordingly, this paper establishes a new SOC -based power sharing algorithm to employ the two power sources to supply DTPMSM. The average traction demand along with the SOC of the LiBC are used as two main inputs for the proposed approach. The system under study has been modelled and evaluated in the Typhoon HIL real time simulator. Comparative analysis is demonstrated at the end of the paper to validate the proposed algorithm.
