Özet

In this study, a power converter was designed to use in electrical appliances the energy generated from renewable energy sources or supplied from the battery packs. This converter consists of a cascade connection of DC-DC boost converter and a single phase full bridge inverter. The DC-DC Boost Converter is used to increase the DC voltage of the battery or renewable energy system and is controlled with the PI, PID and Fuzzy Logic (FL) controllers to keep a constant level the DC Link voltage. The single phase full bridge inverter converts the DC-Link voltage to a two-level AC voltage by using the sinusoidal PWM control signal. The output voltage of the inverter controlled by the unipolar SPWM switching signal contains less harmonics than the bipolar switching signal.
