Abstract :
This paper covers the design and analysis of a compact inverter for photovoltaic (PV) and fuel-cell applications. The inverter is made up of two isolated Ćuk converters working differentially to create a 60-Hz sinusoidal output. This enables direct dc/ac conversion with low device count and yields a simple drive-circuitry. This configuration will lower converter cost and size and can achieve an estimated efficiency of ≥ 95%. Key topics covered in this paper include analysis of the inverter topology and its design.
