Abstract: "The object of this work is to design and build a novel topology of a micro-inverter to directly convert DC power from a photovoltaic module to AC power. In the proposed micro-inverter, a structure with two power stages, which are DC/DC and then DC/AC converters, is used. The inverter is designed capable for future integration of battery as a buffer in between the DC/DC and DC/AC converters. A novel MPPT algorithm is implemented and evaluated in the DC/DC converter to optimize the solar panel energy production. The new method operates with the efficiency of 99.23% which is a 2.5% improvement on the standard method, and a response time of less than 0.2s. A modification of designing the inductor and transformer using Litz wires is also mentioned. The core using Litz wires may reduce the Eddy current effect and is 15% smaller than the coil using a single conductor. In this research the following approach is taken. A literature review was conducted, to identify potential converter topologies. A topology for both converters was selected by comparison of performance through simulations. Maximum Power Point Tracking algorithms were also investigated, to select an appropriate control scheme. A design for two converters was then performed, leading to a prototype for experimental verification". Abstract.
