According to a 2019 Global Market Insights, Wider Band Gap (WBG) devices have made it possible to make small packaged and compact electronic devices which have high power density. The power semiconductor industry is aiming to develop devices with less weight and low-cost creating opportunities for the market.
As conventional silicon-based devices are approaching their material limits, silicon carbide and gallium nitride are becoming more popular and are being adopted across various industry verticals due to its higher dielectric field strength than silicon.
Moreover, wider bandgap and thermal energy allow it to withstand higher temperatures and voltages, making it an ideal substitute for silicon. The GaN and SiC power semiconductor market has significantly emerged as the devices are finding their applications in areas such as PV inverters, hybrid & electric vehicles, UPS and other power applications.
Various power industries are affected by energy loss, particularly during power conversions. Efficiency is a crucial factor for industries to ensure better performance. Limitations to achieve the required efficiency often lead to high costs. As a result, semiconductor industries are focusing on adopting materials with more power-suitable characteristics, giving significant growth opportunities to the GaN and SiC power semiconductor market.
These Gallium nitride power devices hold high growth potential to be used in several power semiconductor applications. The material can be used to enhance the electronic performance and power capacity. GaN offers several benefits over conventional silicon in transistors due to its features such as high-power density, miniaturization of systems and increased efficiency. While silicon has been majorly used for many years in the power semiconductor industry, companies are increasingly focusing on improving GaN device reliability for high power systems. The exponential growth of GaN is expected to drive GaN and SiC power semiconductor market growth.
The semiconductor industry developments are one of the key factors influencing the market. The U.S. is the dominant region considering the market share in the global semiconductor industry with over USD 200 billion in 2018, which is almost half of the global sales according to the Semiconductor Industry Association (SIA). Moreover, the U.S. semiconductor industry spends one-fifth of its revenue for R&D activities, making it an important region for the market.
GaN and SiC power semiconductor market is expected to gain traction in renewable energy applications. PV inverters, which play a crucial role in converting sunlight into electricity, are expected to adopt these devices to gain more efficient power conversion. The SiC embedded PV inverters incur much lower switching losses and increase system efficiency. Use of SiC devices for the PV inverter applications improves power density by minimizing heat dissipation and can also reduce the size of passive components.
