The global solid state transformer market size is anticipated to register a considerable CAGR during the forecast period, 2021-2028. The growth of the market is attributed to the exponential shift from traditional transformer to solid state transformer for enhanced voltage regulation.

Solid state transformer (SST) is advanced electrical energy device that offers bi-directional power flow. It is the amalgamation of high-powered conventional high frequency transformers, semiconductor components, and control circuitry. SST offers a wide range of applications in terms of renewable power generation, voltage regulation, efficient transformation from alternating current (AC) to direct current (DC), and reactive power consumption. Compared to traditional transformers, it is small in size and improves the quality of the power by regulating voltage fluctuations. SST connect the various sources of energy, such as wind power and solar power to power girds and enhances the efficiency of power transmission systems.
The COVID-19 pandemic outbreak had a negative impact on the market. During the pandemic, several transmission, as well as renewable projects have been delayed. Additionally, the SST components supply chain is disrupted across the globe resulting a decline in demand for SST. The market is expected to recover soon with an uptrend operation due to subsiding the COVID cases gradually across the globe.
Market Trends, Drivers, Restraints, and Opportunities
- Growing renewable electricity production across the globe is one of the key factors driving the market growth.
- Increasing investment in smart grid technologies especially in developing countries is projected to boost the market during the forecast period.
- High cost of SST coupled with low consumer awareness in developing countries acts as a major challenge that can restrict the market growth in the coming years.
- Rising concerns about reliability of the SST is expected to hamper the market growth during the projected timeline.
- Escalating investment in R&D of SST by market players is anticipated to create significant growth opportunities for the market.
