Abstract

Power electronic transformers are more and more widely used as energy router in Energy Internet. However, the primary and secondary sides of AC/DC/AC three-stage power electronic transformers all contain large capacitors as DC links. The presence of capacitors severely affects the life and power density of the converter. This paper presents a topology and control strategy for a household energy router based on direct power electronic transformers that reduces the DC link of the PET. It can increase the power density and reliability of the device to some extent. The topology is divided into two parts, one part is AC interface, which is used to connect household AC distributed energy such as micro-turbine, and the other part with capacitor is DC interface which is directly supplied to the household small power DC load. This paper proposes corresponding control strategies for the two interfaces, and carries out simulation and experimental verification.
