This paper proposes a high step-up boost converter family which is based on a switched coupled inductor (SCL) and a voltage litter cell. The derivation of converter topologies of the family using SCL and voltage litter cell is explained in detail. The operation of the converters is explained using the converter which has the highest gain. The operation of the other converter topologies can be explained using a similar approach. The converter with the highest gain is theoretically analyzed assuming its operation in the continuous conduction mode (CCM) to obtain expressions for the static voltage gain, capacitor voltages, voltage stresses of switching elements, inductor currents and boundary mode operation. The operation of the converter is validated using simulation assuming near ideal conditions.
