Abstract A hybrid integrated power flow controller (HIPFC) is proposed in this paper to optimize dc-link voltage rating and converter capacity for cophase traction power supply systems. In contrast to the conventional integrated power flow controller (IPFC), the presented HIPFC behaves advantages in lowering the dc-link voltage up to 55 % and saving converter capacity 14 % when load power factor is 0.86. The system configuration combined with V/V transformer, compensation principles, and characteristic is analyzed. The system parameters for HIPFC are investigated in detail according to traction and regeneration operation conditions. Finally, steady and dynamic simulation results validate the correctness and effectiveness of the proposed HIPFC, which can compensate reactive current, negative sequence current, and harmonic current simultaneously in a broad range of loads.
