摘要：

In order to overcome the disadvantages of existing DC/DC converters in cost and efficiency, a novel hybrid DC/DC converter topology is proposed based on the module serial technology as well as thyristor and diode serial technology. It can be used to connect two HVDC power grids with different DC voltage levels. This paper thoroughly analyzes and demonstrates the working principle, control strategy, parameter design and technique economy of the proposed topology. Finally, simulations in MATLAB validate the feasibility of the proposed DC/DC converter. © 2018 Automation of Electric Power Systems Press.
