Summary This paper presents a new voltage multiplier with a small number of components, composed of a coupled inductor and a switched capacitor cell, which allow four different configurations. To evaluate these configurations, these cells were integrated into the boost converter, thus generating four new high voltage gain topologies. These topologies have different characteristics: thus, the principle of operation, voltage gain, voltage and current stress, and design guidelines of each converter were evaluated. Finally, four prototypes of 30 V/400 V and 200 W were built and evaluated experimentally.

High step-up DC-DC converters are necessary in photovoltaic energy generation, due the low voltage of the panels source. This article propose the Doubler Output Coupled Inductor converter. This converter is based in boost converter and utilize switched capacitors and a coupled inductor to maximize the static voltage gain. The converter achieve a high voltage gain with low turns ratio in the coupled inductor and an acceptable duty cycle. Can highlight the converter utilize low number of components and have low voltage and current stresses in semiconductors. To validate and evaluate the operation of the converter a 200W prototype is simulated.
