Voltage multiplier applied to boost DC–DC converter: Analysis, design, and performance evaluations

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. New voltage multiplier with a small number of components based on switched capacitor and coupled inductor is proposed. Thus, four new high voltage gain converters with low voltage and current stress are generated and evaluated.
