Power Distribution at any Scale – a Task for Power Electronics

6 May 2025

We all enjoy getting electric energy whenever we plug-in a device into a socket, the same way industry in Europe benefits from being interconnected by one of the most reliable grids worldwide. This grid, often referred to as the largest machine mankind ever built, is currently growing, being reconstructed and extended while in operation.

Power semiconductors play a crucial role in this ongoing transformation. Electricity generation in renewable energy systems like wind and solar power are growing quickly, providing a growing portion of the energy consumed. To enhance the grid stability despite the fluctuating nature of these sources, battery energy storage contributes to load shifting and peak shaving. At the same time, electric mobility conquers our streets from small scooters to passenger cars but also to trucks and public transportation. High-power charging infrastructure either demands a powerful backbone to be operated or benefits from being battery-supported when locally the grid’s capacity is limited.

The strong growth in datacenters, driven by the capacity needed for artificial intelligence, puts further new consumers to the end of the energy supply chain with enormous appetite for electricity.

Additionally, decarbonisation efforts based on hydrogen demand huge amounts of energy to drive electrolysis equipment which is also expected to grow massively within the decade to come.

From central energy distribution in the GW-regime to industrial energy usage in MW-scale, charging infra­structure in the hundreds of kW and residential use-cases that cover tens of kW-demand, as well as individual consumption down to a few Watt, Littelfuse offers a wide portfolio of solutions.
Power semiconductors, control- and protection technologies are readily available.
