The energy sector is currently experiencing a revolution thanks to the increasing share of renewable energies on the grid production. However, those sources of energy produce a voltage which is not adapted to the existing grid, making the use of power electronics converters mandatory. On its side, power electronics is also experiencing a revolution, made this time possible by the launch of new wide bandgap SiC and GaN components on the market, enabling the design of much more efficient power converters compared to silicon-based devices. These new components represent a major opportunity for power electronics, even if their full use is still limited by a number of obstacles. When it comes to injecting power into the grid, the main obstacle is the lack of resilience that semiconductor devices have when they need to deal with grid current surge. In fact, protection circuits present on the grid generally have response times which are longer than th...
