Challenge

Rising global electricity demand from AI data centers and modern industries requires smarter and more efficient grids. The traditional grid infrastructure – conventional transformers, protection systems and distribution – was not designed for fast-ramping, hyperscale AI demand. This results in bottlenecks in grid connection, power conversion capacity, reliability and fault protection. 

Solution

Resolving this bottleneck requires semiconductor-driven innovation. Infineon's advanced power semiconductors enable next-generation solid-state transformers (SST) and solid-state circuit breakers (SSCB), delivering the efficiency, power density and reliability that modern AI data centers and industries need. Solid-state transformers are a key step in modernizing grid connections for AI-scale power demand. SSTs enable higher efficiency, less weight and more compact installations than conventional transformers do. SSTs provide a more flexible bridge between the grid and high-power electronic loads for data centers, battery energy storage, solar farms, EV charging and DC microgrids. Solid-state circuit breakers apply this principle to electrical protection by replacing the electromechanical circuit with semiconductor technology. SSCBs isolate faults within microseconds and without arcing, thereby improving the reliability and fault tolerance of the system in high-power environments.

How can electricity travel far and with minimal loss?

Bidirectional Energy Flow

Bidirectional Energy Flow

Challenge

Low-loss transmission of green electricity is crucial to the energy transition. Electricity is often generated far from where it is consumed, for example at an offshore wind farm. When this green electricity is transmitted over long distances, some of it is lost as heat due to resistance in the wires. 

Solution

High-Voltage Direct Current (HVDC) transmits power over hundreds of kilometers with minimal power losses compared to alternating current (AC) systems. Increasing voltage makes it possible to decrease current, which in turn reduces the amount of energy lost as heat. Offshore and onshore converter stations turn AC into DC for the journey via underground, subsea cables or overhead lines and convert DC back to AC at the destination. HVDC offers several advantages such as reduced power loss, improved controllability and grid stabilization. A rough idea of the order of magnitude: More than 16,000 Infineon 6.5 kV IGBT modules can be installed in a single 2 GW HVDC project.

FAQ

Why is power infrastructure becoming such a critical topic now?

Electricity is becoming the foundation of modern life and industry. At the same time, renewable energy sources such as photovoltaic and wind power are becoming a larger part of the electricity mix. Unlike conventional power generation, renewable energy depends on weather conditions, which makes electricity generation more variable and less predictable. Modern power grids will therefore have to be smarter, more flexible, and more resilient in order to balance supply and demand in real time. A resilient grid helps ensure a stable and reliable power supply, even when generation and consumption patterns change rapidly.

What role do semiconductors play in modern power infrastructure with more renewable energy?

Semiconductors are the invisible technology behind the generation, conversion, transmission, distribution and use of electricity. They help control the flow of power, ensuring that energy is delivered efficiently and safely where it is needed. This is especially important given the growing share of renewables: Renewable energy sources such as photovoltaic and wind power deliver green electricity, but their output fluctuates depending on weather and time of day. Semiconductors enable advanced power electronics that help stabilize the power grid by supporting technologies such as battery energy storage systems that balance supply and demand, and grid-forming inverters, which stabilize voltage and frequency throughout the grid.

How do semiconductors improve energy efficiency?

Electrical energy typically undergoes multiple AC/DC and DC/DC conversion stages before reaching the end application. Every conversion stage introduces loss in terms of conduction and switching that impact overall system efficiency. Advanced power semiconductors reduce these losses through lower on-resistance, faster switching characteristics and improved thermal performance. Wide-bandgap technologies such as Silicon Carbide (SiC) and Gallium Nitride (GaN) further increase efficiency by enabling higher switching frequencies and operating temperatures. This not only reduces energy losses but also decreases cooling requirements, lowers system size, and improves overall power density.

Solid-state transformers represent a new generation of grid technology that replaces traditional transformer functions with advanced power electronics. They can be smaller, lighter, more efficient and more flexible than conventional transformers. SSTs make power distribution more intelligent and more adaptable, helping prepare grids for future energy demands. SSTs are expected to become key building blocks in future applications including renewable energy integration, fast EV charging hubs, battery energy storage systems, and high-power AI infrastructure.

What are solid-state circuit breakers and how do they improve reliability?

Traditional circuit breakers rely on mechanical components to interrupt fault currents. Solid-state circuit breakers use semiconductor technology to react much faster, isolating faults in microseconds. This rapid response helps protect critical equipment, reduce downtime, and improve overall system resilience. In addition, they enable advanced monitoring, diagnostics and digital control capabilities. These smart protection systems are becoming increasingly important as power networks become more complex.
