چکیده :

The power quality at the place of consumption is of great importance. Considering the increasing consumption rate, the distance between production and consumption places, sensitive consumers, and also the impact of non-linear loads on the voltage quality of the consumer side, it seems necessary to create a platform for improving the power quality. Variations in over-voltage and under-voltage levels, among other types of power quality issues, are something that must be specifically addressed and dealt with, as they can reduce efficiency and lead to equipment damage. Improvement of the power quality at the place of consumption is why it is necessary to use voltage stabilizers. In this article, a cost-effective bidirectional voltage stabilizer with a new structure for AC voltage level regulation applications is presented, a low number of switches, a simple switching pattern, the possibility of increasing and decreasing the voltage level, the common ground between the load and the network, and the possibility The connection is with and without a transformer are including the advantages of the proposed structure. Presenting the structure of the proposed converter along with its switching pattern, calculations related to the gain, and the Introduction of the types of connection modes of the converter to the network are presented in this article. Finally, in order to check and verify the theoretical relationships, the simulation of the proposed structure has been done using Psim software.
