(57) Abstract :
The present invention discloses a two-stage hybrid selective harmonic elimination method of control for a single-phase adaptive DC
bus eleven-level inverter wherein the first stage of control method implements a metaheuristic technique hybrid particle swarm
optimization which finds the initial solution within specified time while in the second stage of control method, an iterative method
Newton-Raphson is applied for the computation of the optimum switching angles in such a manner that the desired fundamental
output voltage can be obtained while detrimental dominant harmonics can be eliminated simultaneously from the output of adaptable
single-phase DC bus eleven-level inverter. The present invention utilizes the merits of both metaheuristic technique and iterative
method together, which results in the reduction in the computational time and improvement in the accuracy of optimum solution when
applied to selective harmonic elimination problem in the single-phase adaptive DC bus eleven-level inverter.
