Abstract
An electrical interconnection circuit can be used with a solid-state-transformer (SST) system. The interconnection circuit includes medium voltage direct current (MVDC) to low voltage direct current (LVDC) direct current to direct current (DC/DC) converters, independent LVDC buses respectively connected to one of the MVDC to LVDC DC/DC converters, and an interconnecting DC/DC converter connecting at least two of the independent LVDC buses in order to ensure equal power demand from each MVDC to LVDC DC/DC converters. The interconnecting DC/DC converter is configured to re-route power between the plurality of independent LVDC buses. A power rating of the interconnecting DC/DC converter is set according to power to be rerouted from other LVDC buses via the interconnecting DC/DC converter.
