Design Topologies for Hybrid Boosting Converter

The high voltage gain converter is widely employed in industrial applications such as solar PV system, fuel cell, electrical vehicle, and high intensity discharged lamps. This research work has investigated the performance of various hybrid boosting converters used for renewable energy applications and will mostly focused on solar PV system. The design of hybrid boosting converter has gained the advantages of voltage regulation from its boost structure by the gain enhancement from its voltage multiplier structure. Many works are reported for the design of hybrid boost converter which consists of single switch, single inductor by employing bipolar voltage multiplier. This converter has less component stress, small amount of output ripple. The investigations for the performance analysis of the converter achieves extremely large voltage conversion ratio. The design should can boost the input voltage nearly to a significant level with less switches and inductors while maintaining high efficiency.
