Traditionally, low frequency transformers have been used for electrical isolation and voltage matching in the power system, but they are bulky and heavy. Therefore, there is a demand for equipment that reduces the cost, size, and weight of power transmission and distribution systems. Power electronics converters, such as solid-state transformers (SSTs), have been developed to make old and new power systems compatible. SSTs utilize high or medium frequency converters that reduce transformer size and increase power density compared to conventional transformers. Although prototypes of SSTs with high power density and efficiency have been developed using advanced magnetic materials, this technology is still in the research and development phase.
A solid-state transformer, also known as a smart transformer, is an advanced type of transformer that incorporates semiconductor components, control circuitry, and a high-frequency transformer. It enhances the quality of electricity by regulating voltage fluctuations, reduces grid losses, ensures security of supply, and protects consumers from grid failures. SSTs can perform various electrical energy conversions, such as AC-AC, AC-DC, DC-DC, and DC-AC, depending on the specific application. In the future, SSTs are expected to find wide-ranging applications in areas like renewable power integration, traction locomotives, electric vehicle charging stations, and more.
Currently, the solid-state transformer market is primarily focused on research and development. However, it is anticipated that solid-state transformers will gradually replace conventional transformers in the coming years. Solid-state transformers are key components in the development of smart grid infrastructure, as they allow bidirectional power transfer and voltage scaling for different applications. Manufacturers of conventional transformers are also getting involved in the research and development of solid-state transformers to meet the future demand from the smart grid infrastructure.
It is important to note that the COVID-19 pandemic has resulted in a slowdown in research and development across various industries due to funding limitations, disruptions in manufacturing activities, and supply chain interruptions for components and raw materials. Additionally, the pandemic has halted the construction of renewable power infrastructure and smart grid projects, leading to a decrease in demand for transformer products and impacting R&D projects worldwide.
The demand drivers for the solid-state transformer market include an increase in renewable power generation, a rise in the number of electric vehicle charging stations, electrification of rail locomotives worldwide, and the integration of high voltage DC (HVDC) systems. However, the market faces challenges such as the high initial cost of solid-state transformers, technical hurdles, and the lack of basic power infrastructure in underdeveloped countries.
