abstract
- This paper proposes a new integrated charger topology based on a four-phase asymmetric bridge converter and switched reluctance machine. The topology is capable of power factor corrected three-phase charging and both buck and boost output voltage control. No modifications to the machine are required while a limited number of additional inverter components are added. An equivalent-circuit based model of the machine is developed to facilitate investigation of the integrated charger performance. A control strategy for the charging mode is developed. The proposed topology is demonstrated through simulation of two distinct three-phase grid based charging applications.
