Space Charge Measurements for HVDC GIS Spacer using the Thermal Step Method

2018-09-11T14:29:58+00:00August 31st, 2018|High Voltage Substation Equipment, Publications|

High voltage direct current (HVDC) technologies are currently emerging to develop new energy transmission networks able to integrate renewable energy sources with remote locations from consumers. Gas Insulated Substations (GIS) have been widely used in alternating current (AC) transmission due to their low footprint and high reliability.

A 100 kW 1.2 kV 20 kHz DC-DC converter prototype based on the Dual Active Bridge topology

This article presents the design, the fabrication, and the test of an isolated DC-DC converter for renewable energy applications. The converter is based on the Dual Active Bridge topology and uses silicon carbide power semiconductors and a medium frequency transformer. The design process covers hardware ranging from the semiconductor die to the complete power converter. For the control, a rapid prototyping approach was used. The experimental validation of the 100 kW prototype is presented.
