Abstract

Combining the specific harmonic elimination pulse width modulation technology of cascading H-bridge convertor, this paper discusses the function relationships between its parameters, and establishes the corresponding multiple nonlinear system of equations, and focuses on analysis of advantages and disadvantages of numerical computation methods used to solve this system of equations, such as Newton Raphson method, genetic algorithm and particle swarm optimization. Through comprehensive comparison, this paper finds out unknown parameters in improved particle swarm optimization with switching angle initial selection rule used to solve the specific harmonic elimination technology of step wave of cascading H-bridge convertor. This method is of good practical engineering value in preparing the control strategy of cascading H-bridge convertor.
