Possibilities of 2-phase electronic converters for electric vehicle drives

The paper deals with power electronic two-phase pro pulsion system with IM/SMPM motors for electric vehicle drives applications. Th e proposed system consists of two-stage converter comprises: resonant LLC converter with AC output, two-phase matrix converter commutated by HF AC input voltage, and two-phase in duction/synchronous motors. Such a system with AC interlink, in comparison with curren tly used conventional system configurations features a good efficiency of electr onic converters (due to soft switching of both converters) and also good torque-speed charact e istics of two-phase AC motors. Results of simulation compared to experimental veri ficat on carried-out ones are in good accordance between them.
