A Novel Low Voltage Partially Rated Power Flow Controller

This paper proposes a partially rated power flow controller (PRPFC) for the low voltage DC (LVDC) system. One side of the PRPFC is connected in parallel between the two poles of the DC system and the other side is inserted in series with the transmission line to adjust the dc power flow, which bring it the merit that devices only need to bear part of the power of the system. By multiplexing the secondary full bridge, not only the power transmission of DAB but also four-quadrant operation can be achieved. Simulation and experiment results show that the proposed PRPFC is capable of power flow regulation and its dynamic performance is verified.
