Abstract

The efficiency is the important factor for the power converter that is used in photovoltaic application. This paper proposes a new SVPWM method for three - level TNPC topology to improve the efficiency by minimize the number of switching. The proposed method is based on the virtual flux vector. By applying proper non-zero voltage vectors, a quasi circle will be created. The performance of the converter and the comparison of different modulation methods are analyzed. Simulation and experimental results show that the proposed method provides high efficiency.
