The one change that is hard to miss is that the world is becoming more electric. EVs are on the rise, renewable energy is expanding, and data centers are scaling rapidly to support AI and cloud computing. But did you know there is one key technology behind all of this? It is power semiconductors, and today, the top 10 power semiconductor companies are driving this transformation.
With the rising demand for electricity worldwide, their importance is becoming more evident. A recent report by the International Energy Agency states that by 2026, electricity demand is expected to increase by 3.7%. Data centers alone account for almost 1.5% of electricity consumption worldwide.
We can clearly see this shift happening, as the demand for EVs, renewable energy, and data centers is increasing steadily. Total EV sales globally hit 14 million units in 2023, which is a rise of about 35% from the previous year. Renewable energy experienced significant growth in the same year, adding over 440 GW of new capacity.
These numbers are projected to rise in the near future, supported by widespread AI adoption. The aforementioned factors are positively influencing the power semiconductor market, with the market size expected to reach USD 76.57 billion by 2031, as per the latest report published by Kings Research.
To keep up with these shifts, the companies dominating this market are prioritizing innovation. New materials such as gallium nitride and silicon carbide are enabling them to develop more reliable systems.
