Solid State Transformer: Revolutionizing the power grid for power quality and energy efficiency

What Is Solid State Transformer

In actuality, an AC-to-AC converter, also known as a solid-state transformer (SST), power electronic transformer (PET), or electronic power transformer, is a type of electric power converter that replaces a conventional transformer in AC electric power distribution. This type of electric power converter is known as an AC-to-AC converter. Because it works at a higher frequency, this kind of transformer is more complicated than a traditional transformer that uses the utility frequency, but it also has the potential to be more space-efficient and smaller than a traditional transformer. The two primary varieties are referred to as "real" AC-to-AC converters and AC-to-DC-to-DC-to-AC converters, respectively. The AC-to-AC converter or DC-to-DC converter that is often found inside of a solid-state transformer is really a transformer. This transformer is what provides the electrical isolation and carries the entire power. This transformer is more compact because the DC-DC inverting stages that occur between the transformer coils are on the smaller side. As a result, the transformer coils that are needed to step up or step down voltages are also on the smaller side. Active regulation of voltage and current may be performed via a solid-state transformer. There are several that are able to convert electricity from single-phase to three-phase and vice versa. The amount of conversions that need to take place may be decreased by having variations that can either input or output DC power. This results in increased end-to-end efficiency. A Modular Solid-state transformer is similar to a Multi-level converter in that it is made up of numerous high-frequency transformers and has the same function. Because it is an intricate electrical circuit, it has to be constructed such that it can survive surges of various kinds, such as lightning. The solid-state transformer is a relatively new kind of transformer.
