| dc.description.abstract | This thesis present a single phase H-bridge grid tie inverter developed for photovoltaic application. The objectives for this design are simplicity, efficiency, stability and compact size. Base on these objectives, the H-bridge inverter topology is chosen to be the design. Besides that, LC passive harmonic filter is used to remove the harmonic contains and a grid frequency transformer is used to step up the output voltage of the inverter to the grid voltage. Moreover, hybrid switching technique is chosen to be the switching topology of this designed inverter. This hybrid switching technique is a technique that combines the high frequency SPWM and grid frequency square wave. An analog circuit is build to generate the control signal needed for this switching technique with major components of this control circuit are Op-Amp. The advantage of this switching technique is the reduction of switching loss of the inverter. Besides that, this switching technique helps to eliminate the freewheeling diode in two of the MOSFETs used in the inverter. In order to verify this design methodology, the grid tie inverter is tested in two stages; simulation and prototype testing. In the simulation stage, MATLAB Simulink is used. After the simulation, a prototype is built and tested under the stand alone as well as grid tied conditions to verify the accuracy of the design. For the prototype built in this thesis, the maximum power output is 70W. However, the maximum efficiency of this inverter is 92%, which happened at 60W output power. | en_US |
