The emergence of the power semiconductor industry is continuously on the rise, especially as compared to its growth a decade back. Trends such as smaller transistors, Wide Bandgap semiconductors, and a focus on sustainability have been driving the industry in recent years. Increasing shifts towards energy-efficient solutions are centralising the use of semiconductors in powering advancements across key sectors.
The power semiconductor industry, a critical sector, plays a pivotal role in energy management, electronics, and power conversion systems. These tiny yet powerful components are crucial in handling high voltage and current, enabling advancements in the automobile industry, renewable energy systems, and smart devices. As the world shifts towards more energy-efficient solutions and sustainable technologies, the power semiconductor industry is experiencing rapid growth. A study by MarketsAndMarkets projects that the semiconductor industry is set to surpass $1 trillion by the end of this decade, underscoring its significant role in the global economy.
Here’s more on what the future looks like for the power semiconductor industry in a world that is fuelled by digitisation and technological advancements:
Smaller Transistors and Miniaturisation
One of the most significant trends in the industry is the push for smaller transistors and miniaturised power devices. The use of power semiconductors is particularly relevant in maturing industries like consumer electronics, electric vehicles, and industrial automation. By making the size of the transistors compact, manufacturers can create more compact and efficient components that fit into smaller devices. The trend enhances power density, improves thermal management and, most importantly, reduces energy consumption, all while boosting performance.
Wide Bandgap Semiconductors (WBG)
The introduction of Wide Bandgap Semiconductors, such as Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductors, is a game changer for the ever-growing power semiconductor applications devices. These smaller yet powerful materials have superior characteristics as compared to traditional silicon-based semiconductors, offering superior performance, faster switching speeds, and the ability to outperform at higher temperatures. These semiconductors are particularly beneficial for high-power applications, including EVs, solar inverters, and industrial machinery.
Sustainability and Energy Efficiency
Sustainability and energy efficiency are at the heart of every innovation today, and the power semiconductor industry is a shining example of this. As concerns over climate change and energy consumption increase with every passing day, the semiconductor industry is developing solutions that help reduce the carbon footprint of various applications. Power semiconductor devices enable energy-efficient systems, such as renewable energy installations, smart grids, and EVs, contributing significantly to a greener Earth and inspiring hope for a more sustainable future.
Global Chip Shortage and Demand for Microchips
The global semiconductor shortage has profoundly impacted the power semiconductor industry. The global COVID-19 pandemic disrupted supply chains, causing delays and shortages in semiconductor production. This highlighted the critical importance of microchips in all types of electronics, from automotive to consumer electronics. Hence, governments worldwide have been implementing policies to strengthen local production and reduce dependability on foreign suppliers.
To conclude, as the power semiconductor industry evolves, it is quite evident that its impact will reach far beyond individual technologies and sectors. In the bigger picture, the power semiconductor industry is not merely adapting to current trends but actively shaping the future of electronics, energy management, and technology. As we step towards a more digitised and sustainable world, the role of power semiconductors will become increasingly central, making its impact significant in innovations that address both environmental and technological challenges. Mitsubishi Electric India is a popular manufacturer of semiconductors and devices for various industries, delivering high-efficiency products that are manufactured to support sustainability.
