A PFI Bridgeless Canonical Cell Switched Converter based SRM Drive for Battery Driven Vehicle Applications

This study presents a power factor improved (PFI) canonical cell switched (CCS) converter fed switching reluctance motor (SRM) drive. The presented power factor improved converter is configured in a bridgeless scheme because of which the drive does not require any rectifier and thus became compact and also the losses corresponding to rectifier also got extinct. The presented CCS converter is adorned with certain extra benefits like elimination of two extra external diodes which are generally required by bridgeless schemes, usage of single tapped inductor in place of two distinct inductors. The presented SRM driver uses disrupted (not continuous) inductor current conduction mode which need only a single voltage sensor to sense dc-link voltage unlike other mode in which 3 sensors are needed for control. The present study uses SRM motor because of its lower-cost and fault tolerance nature. The Simulink model of SRM driver is developed at MATLAB 2018a platform and simulation results are deployed and discussed to validate the driver.
