Inverters allow the use of residential solar power to run household appliances and electronics by converting DC to AC power just like the AC power from the grid. This study looks at the design and implementation of a novel multilevel inverter topology called a single phase interconnected H bridge inverter. By utilizing reduced switching complexity, the multilevel inverter can lower the cost of a typical inverter without sacrificing the power quality. The design is developed and analyzed through simulation and hardware testing to demonstrate a working model. Load testing is performed on the inverter output as well as analysis of a custom filter to optimize the output total harmonic distortion (THD). Results from measurements done in simulation and hardware demonstrate the functionality of the proposed inverter topology, providing quality outputs at no load condition. The thesis will also identify and offer solutions to the problems encountered during the construction and testing of the proposed inverter.
