systems with an independent application in electronics, there is a need for the existence of a system that can feed these loads. compared to the conventional three - phase inverters, the load - neutral wire is connected to the middle of the dc link, the four legs require less capacitance. due to the existence of possible nonlinear and non - linear (independent and nonlinear)systems, the need for proper controllers for this inverter is one of the most important issues in an independent application.
one of the ordinary controllers which is used in three phase inverters is the predictive controller. one of the common disadvantages of predictive controllers can be delayed due to the number of input voltage vectors that are used in the cost function and high switching frequency. It is a predictive model that can be used to reduce the switching frequency from additional hypothetical data vectors, which increases the delay in the function calculations. to reduce the delay, some sliding mode controllers have been used. To demonstrate the performance of the proposed controller, the controller is simulated for a three - phase inverter in the simlulink software environment, indicating that the number of switching vectors in the cost function is reduced at a maximum of 13 and the average switching frequency has been improved by 10 % and does not appear in the total harmonic interference value, indicating the superiority of the proposed model relative to the previous used models.
