CUP converter: A design guide for the new topology

This paper presents a new topology for AC-DC grid-tie inverter in renewable energy application. The simple switch configuration is built around a filter-like energy storage cell to isolate and decouple the operation of the three half-bridges. The intra converter storage is built around the coupled inductor principle, allowing therefore for lower switching frequency, lower voltage stress and shared current across the components. The sequence of operation, along with the design and sizing of the circuit components will be presented before getting to the simulation results. The simulation results confirm that is new topology offers flexible and versatile behaviors and for the same components is more efficient than other topologies.
