Transformerless Small Wind Turbine Based on PMSG With Switched Boost Inverter

In this paper, the analysis and modeling of an integrated system of a small wind power plant without a transformer based on Permanent magnet synchronous (PMSG) with switched boost inverter (SBI) is proposed. Then theoretical calculations related to SBI performance in different operating modes are presented. Finally, a small wind turbine system based on PMSG is modeled for off-grid load, and in order to show the performance of the system and confirm the correctness of the theoretical calculations, the presented configuration is simulated in PSCAD/EMTDC software and the results are presented in detail.
