In this 9-level SC inverter, there are 3 pumping capacitors between supply source and output terminals in order to realize the maximum boosting gain of 4 at most, and also to obtain the inverted gain of 4 with the help of bidirectional switches employed here. For achieving a staircase ac output, these bidirectional switches are controlled with the driver signals from the clock generator so as to boost/invert the output up to 1x, 2x, 3x, or 4x voltage of supply source. In this paper, an AHE approach is suggested and used for the consideration of the 3rd, 5th, 7th harmonic elimination not only to control the time intervals of the different output levels of 1x, 2x, 3x, 4x, but also to enhance the output regulation capability for the different desired outputs. Finally, this 9-level SC boost inverter is designed and simulated by OrCAD, and all the results are illustrated to show the efficacy of the proposed scheme. In this study, the boost dc-ac inverter is simulated via OrCAD v10.5, pspice and some cases discussed, including steady-state response and dynamic-state response for some variation. Finally, a prototype is also constructed and experimental results are presented to verify the feasibility of the proposed converter. Yuen-Haw Chang 張原豪 2011 學位論文 ; thesis 131 zh-TW
