ABSTRACT
Abstract: This paper proposes a generalized formulation for Harmonic reduction-Pulse Width Modulation (HR-PWM) control suitable for high-voltage high-power cascaded multilevel voltage source converters (VSC) used in constant frequency utility applications. This utilizes the merits of the genetic algorithm (GA) in finding the optimal solution to the nonlinear equation system with fast and guaranteed convergence. This deals with different operation points for both five and seven level converters. The solution to the harmonic minimization problem using genetic algorithm optimization is determined
