Abstract—In response to the need for a more efficient wind energy conversion, multilevel converters have been accepted as promising options in the Medium Voltage Wind Energy Conversion System (WECS). In this paper develop a new medium voltage power converter topology that uses a diode rectifier, a Boost converter and a 5-level multilevel inverter for a wind energy conversion system based on High power permanent magnet synchronous generator. The Boost converter on the generator side tracks the maximum power point and the voltages of the DC link capacitors, while the Multilevel inverter on the network side regulates the voltage, frequency and reactive power of the CC bus of the network. A significant improvement in the power quality of the network is achieved, since the Multilevel inverter no longer controls the voltage of the neutral point of the DC link. These predictions are evaluated using two independent cost functions, and the switching states that minimize these cost functions are selected and applied directly to the generator and network side converters. To comply with the high power application, the switching frequencies of the Boost converter are minimized and kept below 1.5 kHz, respectively. The proposed topology and control strategy are verified through the MATLAB simulation.
