The Selection of the Optimal Solution for SHEPWM under the Influence of IGBT's Manufacturing Technology and Power Losses

Abstract:

The paper proposes a method for the selection of the optimal solution among different feasible solutions of the SHEPWM nonlinear model. The method regards the power losses of the switching devices as a criterion for evaluating the possible groups of solutions. The overall power losses are calculated under each combination of the switching angles at first. The variation track of the power losses that could determine the optimal solution under the specific value of m is presented later. The simulation results contrast the new method with the traditional THD method. A comprehensive evaluation considering both methods was concluded at last.
