An Isolated Zeta Converter Topology for Switched Reluctance Motor Drive with Power Factor Correction

Objective: This paper presents an isolated zeta converter fed switched reluctance motor(SRM) drive with power factor correction for low power applications. Methods: A single phase AC supply is given to the diode bridge rectifier followed by a isolated Zeta converter then frontend converter with Switched Reluctance Motor (SRM) drive. Findings: To design the Power Factor Correction (PFC) isolated Zeta converter operated in Discontinuous Conduction Mode (DCM) for low power applications. For better current regulation, the input voltage is boosted without using any voltage are current sensors, we get both current and voltage wave forms are in phase. Improvement: For many variable speeds drives applications, the presented topology makes it a better choice due to power factor correction.
