In this article, a novel rectifier is designed for two three-phase sources with single-phase inverter and three-phase inverter. The proposed configuration results in back-to-back converter with the dual input source. The main objective is to reduce the semiconductor components in the rectifier. The rectifier design consists of six diodes and three split capacitors. A separate direct current link capacitor is eliminated due to the presence of split capacitors. The simulation model of rectifier and inverter is designed in Multisim, a PSpice-based power electronics simulator, and interfaced with LabVIEW, a graphical programming language for co-simulation. The co-simulation enables the user to utilize two simulation engines for better analysis. The hardware prototype is fabricated and tested for rectifier and inverter. The co-simulation and hardware results proved that proposed design is capable to use in back-to-back converter applications
