Abstract:
Aiming at the applicational requirements of DC electrical transmission,the paper proposes a modular inputparallel output-series connected converter topology for HVDC transmission system. Main circuit topologies and control methods are analyzed. The proposed structure has the following features: a) power is transferred mainly by DC transformers, b) the output power is regulated by series resonant phase-shifted full bridge converters which are based on current closed-loop control,c) both DC transformers and power regulation modules are operating at constant frequency,d) modularization structure is flexible. The simulation and experimental results verify the effectiveness of the proposed structure.
