【 摘 要 】

This paper presents a high efficiency step-upDC-DC converter for low-DC renewable energy sources.The proposed DC-DC converter is controlled byasymmetrical pulse width modulation(APWM) techniqueand achieves Zero-current switching(ZCS) of all outputdiodes. Compared to the previous DC-DC converters, thevoltage stresses of the semiconductor devices can be reducedin the proposed converter. Simulation results areobtained from a 200 W output power. The proposed DC-DCconverter achieves a high efficiency of 97.5 % at the ratedload.Further project has been extended to three phase grid tie inverter using sinusoidal pulse width modulation technique.
