Solid-state transformer (SST) is an emerging technology which can replace large conventional power transformers with semiconductive control and smaller circuit board transformers. They will also become part of the Smart Grid in the future, enabling the most efficient route possible to direct power from any source towards any direction.
Solid State Transformer (SST) is also known as a smart transformer in addition to some communication capabilities. A solid-state transformer is a conventional electrical power system providing two directions power flow within the micro-grid.
Solid-state transformer (SST) is an accumulation of powerful semiconductor components, traditional high-frequency transformers and control circuits that are used to give the power distribution networks an unnatural state of adaptable control. SST technology can step up or step down AC voltage levels simply as that of the traditional transformer, yet it additionally offers a few noteworthy advantages.
A large range of applications uses solid-state transformers, allowing a smooth transition from AC to DC and DC to AC, apart from the conversion of voltage.
However, the most prevalent use of solid-state transformers, however, is alternative power generation. Solid-state transformers are ideal for a wide range of applications, from alternative power generation to traction locomotives, electricity grids and electrical industries.
In contrast to a traditional transformer, the solid-state transformer offers an option for the required DC output. In a typical solid-state transformer, the input voltage is transformed to high-frequency AC using an electronic-based power converter and then fed to the primary side of the high-frequency transformer. On the secondary side of high-frequency transformers, the opposite process is performed to load the desired AC or DC or both forms of output. The high-frequency power transfer leads to weight reduction and size reduction.
Many of the advantages of solid-state transformers come from size reductions. There are many advantages of SST transformer due to its small size. The installation of a transformer isn’t a simple assignment as it needs site preparation, installation and transmission costs all are added to the financial plan.
In comparison, it could be fairly easy to install smaller, cheaper solid-state transformers in small solar plants. The quicker changing pace of solid-state devices would make the management of multiple energy sources in the grid simpler because more transformers monitor and change the power quality. It is a very useful resource for distributed energy and energy storage equipment.
