Abstract

DC supergrids will require DC substations that can interconnect and isolate multiple DC lines and ideally also provide DC voltage stepping. As a possible solution to these challenges, a new resonant DC/DC converter family has been researched recently. This article reports on a 30 kW 200V/900V prototype DC/DC converter built at the University of Aberdeen. The converter tests demonstrate bi-directional power control, operation at various voltage levels and gains, as well as inherent DC fault isolation. The tests with most severe DC faults on the high voltage DC terminals, show that such a fault is not propagated through the converter and no over-currents or over-voltages are experienced. The use of this type of converter can eliminate the need for DC circuit breakers. This paper outlines the design of the prototype converter and explains some practical solutions related to inductor and snubber design.
