摘要：

In this paper a novel power converter capable of extracting maximum power from solar photovoltaic panels is described. It employs a combination of a voltage controlled voltage source inverter and a current controlled voltage source inverter, connected in series on the DC side and in parallel on the AC side. This dual converter is able to provide uninterruptible power supply feature, load voltage stabilisation, unity power factor operation, maximum power point tracking as well as reactive power support. The overall efficiency of the proposed converter is higher than the conventional system with a dc-dc converter between the PV panels and the battery.
