Power semiconductors

Power semiconductors are specialized chips that manage and convert electrical power, enabling efficient energy use in electronic systems.

What it is

Power semiconductors are electronic components designed to handle high voltages and currents, performing crucial functions like switching, converting, and regulating electrical power. Unlike logic chips that process information, power semiconductors are focused on energy efficiency, ensuring devices receive the correct amount of power while minimizing waste. They are fundamental to nearly all electronic systems.

These chips are critical in applications ranging from electric vehicles and renewable energy systems to industrial motors and data centers. Their efficiency directly impacts energy consumption and operational costs. Advances in materials like silicon carbide (SiC) and gallium nitride (GaN) are improving their performance, leading to smaller, more efficient power supplies. Demand for power semiconductors is growing rapidly with electrification trends.

Why it matters

Power semiconductors are vital for energy efficiency in everything from EVs to data centers; their advancements can reduce energy costs and enable new technologies.
