Abstract

To support the integration of more PV sources with utility grids, there is a need for low cost and efficient power electronics converters. In this paper, the structure of cross-switch multilevel inverter (CRM) is proposed to interface more than one PV modules with a resonant converter. CRMs treat each pair of PV modules as one unit during the positive and negative half cycles and this could go against the need to track the maximum power point of each PV module individually. In this paper, a control method is proposed to achieve MPPT of individual modules. Basically, the paring of PV modules in the positive half cycle is made different from that in the negative half cycle which allows the MPPT of each module to be achieved effectively. Moreover, the MPPT of the modules is achieved through distributed controller to enhance the system scalability. Through simulation studies, the effectiveness of the proposed system is verified and its advantages are clearly demonstrated.
