Single phase inverter for pv stand alone application / Siti Humaira Wakhiddudin

Power electronics is application and conversion of electric power. Powers electronic need some of the semiconductor devices to convert electric power from one form to another form. The example of Semiconductor device is a transistors, diodes, and thyristors. One of the converter types are an inverter. Inverter refers to the DC input signal convert to AC output signal. This project is about how to design a single phase inverter for photovoltaic (PV) standalone application circuit with Sinusoidal Pulse Width Modulation (SPWM) as switching technique. In this project, IGBTs are used as the switching. SPWM are applied to IGBT gate driver. PSIM is used as a software simulation to simulate the single phase inverter. This project will be represented in two parts which are single phase inverters for PV application with simulation and hardware construction with include microcontroller circuit. In this project, the PIC 16F877Awill be used as microcontroller circuit and driver circuit. The low pass filter is implemented before the step up transformer to filter the harmonic component. The output from the hardware will be compared with the output from the simulation.
