Inductor coupled converter (IC/sup 2/) for high-power DC-DC applications

The suitability of the inductor coupled converter (IC/sup 2/) and its extension is analyzed for high-power DC-DC conversion. Moderate device and component stresses and zero-loss switching, make this converter a good candidate for applications where both voltage step-up and voltage step-down are required. Analysis shows that, due to the circulating currents, device current rating is a limiting factor in the scalability of this topology to very high powers. Simulation and experimental prototype results are included to demonstrate the operation of the converter.<>
