Abstract
The purpose of this article is to improve the efficiency of the single-phase PWM DC-AC inverter based on the optimization of the switching-phase of the PWM. The improvement means to improve the quality of the output waveform, the efficiency of the conversion, and the reduction of the switching-loss. We propose a novel evaluation function. We search the minimum value of the function by using cuckoo search. We set a criterion of each index to improve the efficiency. As the result, the proposed algorithm can reduce high harmonic components in the switching numbers smaller than the conventional triangle wave comparison method. Also, we confirm that the algorithm can improve the quality of the output waveform and the efficiency of the conversion.
