Transformer box power generation and energy storage system

What are medium and high frequency transformers used for?

Medium and high frequency transformers embedded into power electronic converters are required to provide isolation and and/or voltage matching and used in different applications such as renewable energy systems, electric vehicles, uninterruptible power supplies and energy storage systems , , , , , , .

What is a solid-state transformer?

Solid-state transformers, unlike conventional transformers, act as an active element in the network.

What are the advantages of a solid-state transformer?

In Reference 106, a new model for solid-state transformers is proposed; one of its advantages is better power factor correction and voltage regulation. The proposed model eliminates voltage sag and voltage swell using the existing STATCOM in the distribution network.

Why are Transformers bulky?

Thanks to silicon steel (SiFe) alloy core materials, conventional transformers are designed for grid-frequency (<100 Hz) power systems and operate at a flux density value which is very close to its saturation point. The minimum core area and volume become quite large, and thus, resulting transformer size becomes bulky.

Does a three-phase solid-state transformer improve power quality?

In References 103, 110, a mathematical model of a three-phase solid-state transformer is presented that investigates the effect of SST on power quality improvement.

How a medium frequency transformer has been extended?

1. Introduction Use of medium frequency transformers have been extended by the realization of improved power switches and core materials. New generation power switches are designed to operate under higher voltage and frequency compared with the former ones. New core materials and sizing methodology also help to minimize the transformer design.
