A Tri-directional power electronic transformer for photo voltaic based distributed generation application

Expanding the size and demand of the electrical network, make the use of distributed generation inevitable especially, when the produced power can be expected as a green power. Furthermore, this growth in size brings up the importance of volume and weight of instruments, used in. Power electronic transformer is an attempt to reduce the weight and occupied space of the electrical devices. In this paper, the combination of these concepts leads to make a new, very controllable structure. The good performance of the proposed circuit is shown through several simulations and experiments. Simulations are carried out in PSCAD/EMTDC software.
