Abstract: This research paper is about proposing and discussing the concept of an interleaved coupled-inductor boost converter for locomotives. Two switches in the proposed converter can be simultaneously switched ON and OFF by interleaving the inductor in the converter. The main advantage of this type is better efficiency, fewer components, and cost. The voltage across the two inductors is altered at the same time by coupling the inductors. This method reduces volume and cost of the circuit. Interleaving topology reduces the current ripples while the cascading method reduces the voltage ripples. Hence the converter functions and efficiency can be improved. The simulation analysis of the proposed converter with different controllers has been studied and verified in this paper.
