Moreover, density of space vectors in the space vector diagrams for high resolution inverters is very high and that computation of dwell times may not be necessary. So, nearest space vector approach is used for controlling high resolution inverters. This paper presents a different approach to find the nearest space- vector algorithm for high-resolution multilevel inverters. The method finds coordinates of all the space vectors in the vicinity of a given reference space vector and determines the nearest one and thus controls the inverter. Working of the control strategy is verified by simulations in MATLAB/Simulink Index Terms— Space-vector control, trinary asymmetric ratio, nearest space-vector 2021 6th International Conference for Convergence in Technology (I2CT) Pune, India.
