In this paper, the control design for the grid-connected converter used as a part of the wind turbine generator is discussed. First, the three-phase T-type multilevel converter, which exhibits several advantages such as low total harmonic distortion, reduced voltage stress, and switching loss, is employed for the power stage. Second, finite control set model predictive control (FCS-MPC) is adopted to achieve a multi-objective optimization solution for the inner grid-connected current control loop.

The VIENNA converter is best known for using the fewest semiconductor devices. The purpose of this paper is to do a comparative analysis of the overall loss of the 5-level VIENNA converter, and to compare the fault tolerance of this converter with equivalent 5-level Stacked multicell converter (SMC).

This paper presents a new multilevel topology based on cascaded hybrid multi-level (HCS) inverter. There are different topologies for cascaded inverters for reducing the switches, power loss. The output voltage is increased and the number of switches is reduced with the HCS inverter. Due to this reduction in number of on-state switches, power loss and voltage drop is reduced. Simulation results for 11 level symmetric form of converter is described.
