Brief introduction:

Generally, “additional power conversion stages consisting of DC-DC converters should be connected to DC-bus in SST-based XFC stations in order to charge multiple electric vehicles (EVs) simultaneously”, but incur construction cost and power loss. “This paper proposed the individual module power transmission (IMPT) in SST-based XFC stations to solve the problem.” And the simulation results using DSIM verify the validity of the proposed IMPT.

Verify individual module power transmission (IMPT) control with DSIM

“The proposed IMPT was verified by simulation using DSIM.” The topology configuration is “based on the down-scaled SST consisting of three modules. Modules of the down-scaled model are composed of a cascaded H-bridge (CHB) converter and dual-active bridge (DAB) converter.” The paper shows the simulation results of IMPC when module output powers change and its zoomed waveform using DSIM. And the simulation results show output voltages and switching reference voltages of H-bridges.
