“…From this perspective, it is normally assumed that DC nanogrids are interfaced with AC grids by a central AC/DC converter [19]. In literature, DC distribution grids are considered to have DC/AC inverters for each costumer, allowing the usage of legacy AC devices [9,20].…”

“…An ICT system is also needed in a low-voltage direct current (LVDC) electricity distribution system. The LVDC smart grid concept is presented in [3], [4], and a highfrequency (HF) band PLC concept based on the HomePlug 1.0 specification has previously been proposed and tested for the LVDC system [5]- [7]. It has been shown that HomePlug 1.0 could be suitable for the LVDC system, while the signal is repeated every 500 meters in the cable network.…”

It has been shown that high-frequency (HF) band power line communication (PLC), that is, the HomePlug 1.0 specification, is feasible for a low-voltage direct current (LVDC) smart grid (SG) system, where power electronics and low-voltage DC are applied to the electricity distribution. In this paper, the applicability of the latest HomePlug specification, Green PHY (GP), is studied within the LVDC PLC concept. Channel characteristics between 2-30 MHz in the HomePlug GP frequency band and noise in the channel from the terminals of the PLC couplers are measured. Furthermore, data transmission tests with HomePlug GP compliant modems are carried out in the LVDC laboratory setup and on the LVDC research site.

“…In the LVDC distribution research site [6], galvanic isolation is achieved by using a 50 Hz transformer at the CEI output, although it was clear from the beginning that it is not a feasible option because of the price and physical size of the 50 Hz transformer. The drivers were a simple implementation of the galvanic isolation and the CEI output neutral (N) connection, because the CEI has to be able to supply unbalanced and pure single-phase loads.…”

A low-voltage direct current (LVDC) distribution system comprises a rectifier, a DC network, and customer-end inverters (CEI) responsible for the AC supply to the electricity end-users. The CEIs can be implemented as single-phase or three-phase ones; in this paper, feasible single-and three-phase topologies are introduced and their losses are calculated using nine different power switches. Three commercially available IGBT, MOSFET, and SiC MOSFET power switches are selected for comparison. In this application, a galvanic isolation between the DC network and the customer is required. The isolation is implemented by using an isolating DC/DC converter at the CEI supply, and therefore, the input voltage of the CEI can be different from the DC network voltage. In this paper, the effect of the supply voltage level on the losses of the CEI is calculated for the nine power transistors in single-and three-phase topologies.
