Abstract
This paper proposed a programmed pulse width modulation strategy for two-level voltage source inverters based on the on-line programming of the special solutions of the volt-second balance equations with multi-objective satisfactory optimization (MSO-PWM). The global optimum special solutions for the targets that linear modulation range extension, current ripple losses minimization and switching losses minimization were respectively obtained by solving the established mathematic programming model. Meanwhile, the contradiction between different targets was analyzed in nature. The satisfactory optimization with the process of relaxing the satisfying degree of single object was introduced to avoid the insoluble phenomenon caused by the contradiction, thus realizing the three-objective satisfactory optimization. Compared to the existing local optimization pulse width modulation strategies, the MSO-PWM can adjust the importance of single objective flexibly by selecting an appropriate switching loss coefficient limitation according to the preference of the decision maker to satisfy the demand of different fields, which make it universal and flexible. In addition, MSO-PWM can give consideration to other targets when focus on the most important target, thus, it can achieve multi-objective satisfactory optimization. Experimental results show that the proposed strategy is effective and flexible.关键词
