This paper proposes unidirectional, isolated, DC-DC converter intended to act as an interface between high/medium voltage bipolar DC grid (or two separate DC grids) and another DC grid of an arbitrary voltage level. With the aim of achieving galvanic isolation, along with voltage matching, Scott transformer connection is employed. Furthermore, medium frequency operation of the isolation stage is considered, leading to an increase in converter’s power density. The proposed converter combines two series connected full-bridge modular multilevel converters, within the high/medium voltage stage, and conventional three-phase diode rectifier, within the low voltage stage, by means of the Scott transformer connection. In order to present basic operating principles and evaluate the proposed converter performance, simulation results of 40kV/1.5kV, 10MW system are presented throughout this paper.
