A novel control strategy for ac-dc-ac converter without electrolytic capacitor is proposed to settle the disadvantage of the traditional converter caused by large electrolytic capacitors. This study is developed in four parts: first, after analyzing for the large electrolytic capacitor defect, one novel electrolytic capacitor-less converter and its control strategy are proposed; second, the efficiency of voltage conversion for the novel converter is deduced and compared with the conventional converter, third, the mathematics model of the converter is built; forth, some simulation tests are carried out to verify the performance of converter. The simulation results show that the proposed converter is valid.
