Solid-state transformers can be used to develop an efficient and reliable 800 V DC charging infrastructure for electric vehicles.

Drivers: Rising Smart Grids Market

A smart grid is an upgraded electrical grid made up of numerous automation and information technology systems that monitor and control power transit between two places of consumption in real-time. Solid-state transformers are a crucial part of smart grids as they operate autonomously, adjust voltage, and maintain an interface with the smart grid, allowing remote management and feedback.

Solid-state transformers in smart grids reduce energy use over time by providing real-time monitoring and feedback, lowering greenhouse gas emissions. Another element contributing to the solid-state transformer market growth is the power protection it offers in the smart grid. Solid-state transformers are increasingly being used in smart grids because of these considerations. Furthermore, as power networks become more modernized, demand for smart grids is increasing globally.

Market Restraint

With the usage of high-powered power electronic components and streamlined technology, solid-state transformers are now more expensive than other types of conventional transformers. Solid-state transformers have a high implementation cost, limiting the market expansion. Furthermore, solid-state transformers adoption is likely to lower significantly in undeveloped and underdeveloped nations. Solid-state transformers are seen as a critical enabler for the development of upcoming electric power systems. As a result, the price will likely fall in the future, owing to proactive government activities and increased product knowledge. Market growth is expected to be further hampered by the lack of understanding of the application of semiconductor transformers in various applications.

Market Opportunities

The solid-state transformer technology is nascent compared to traditional transformer technology; periodic enhancements in many design aspects will improve solid-state transformers' functionality and lifespan cycle. Since they are made up of various high-powered power electronic components, any advancement in these areas will benefit the solid-state transformer market throughout the projected period.

Various research institutes worldwide are actively engaged in solid-state technology research and development.
