Design and Implementation of DC-DC-AC Converter

Abstract: Due to wide-range low dc output voltage, the renewable energy sources cannot support the ac or dc electrical appliances directly. Consequently, a step-up converter is required. Currently using photovoltaic systems has several energy conversion stages. As the conversion stages increases power loss, switching loss and harmonics increases. So as to overcome these disadvantages, a new DC-DC-AC converter has been proposed in this paper which exhibits several advantages, the most important of which is the ability to generate both DC and AC outputs higher than the DC source voltage in a single stage with reduced number of switches. So the DC-DC-AC converter can connect the renewable energy sources directly to AC and DC equipment’s. The proposed technology has wide range of applications including industrial, domestic, agricultural, marine etc. The simulations were done in MATLAB/Simulink and both the DC as well as AC output voltages obtained from DC-DC-AC converter were verified.
