The solid state transformer – an essential device in the evolution of DC railway electrification systems
Author / Editor: Philippe Ladoux / Nicole Kareta
Currently, electrical network, research laboratories operators and electrical equipment manufacturers are considering the use of direct current in electrical power distribution. In fact, renewable energy sources and associated storage devices are easier to integrate into a DC grid. Thus, new microgrid concepts are emerging with medium voltage direct current (MVDC).
Currently, new micro-grids concepts at medium-voltage direct current (MVDC), are emerging. The same concept can be envisaged for railway electrification.
