The traditional power transformer typically operated at low frequency with the bulky size either working with step-down voltage or step-up voltage in power system. Aiming to reduce the size of this transformer structure, the solid-state transformer (SST) is suggested. In brief, SST is an ac-to-ac power electronics circuits that operate in high switching frequency offering higher efficiency. Implementation of the smart-grid concept can be made faster than expected with the introduction of SST technology. To-date, there are plenty of power converters that incessant proposed to be used on SST technology. The benefit in term of the structure will give the smaller size and less weight if compare with magnetic transformer. On the other hand, it will impact the cost of equipment and transportation during the installation process. This project will review one of the multi-stage power converters for SST technology of three-phase power system introduced in term of important indices by using a matrix converter. The aims of this project to simulate and analyses the performance of a matrix converter as the ac-ac converter in SST technology.
