Three Input DC-DC Boost Converter for Hybrid Power System with Multilevel Inverter

Abstract:

A new three input DC-DC boost converter fed symmetrical multilevel inverter is proposed. The converter interfaces two unidirectional input power ports and a bidirectional port to battery in a unified structure. This converter uses hybrid alternative energy source such as Photo Voltaic (PV) source, Fuel Cell (FC) source, and Battery. Supplying the output load, charging or discharging the battery can be made by the PV and the FC power sources individually or simultaneously. The proposed structure utilizes only four power switches that are independently controlled with four different duty ratios. Proposed inverter uses two cells for five level output. Boost converter provided hybrid sources to multilevel inverter. Here we promote inverter for attain a pure sinusoidal harmonics free ac application.Key Words-Photovoltaic/fuel cell (PV/FC)/battery hybrid power system, three-input dcdc boost converter.
