Abstract:A kind of integrated topology of charging and drive is proposed for medium/high power-level electric vehicles (EVs). Charging system and motor drive system can be integrated through the same power devices. Three-phase combined full-bridge converter based on magnetic-combination transformer is adopted in the charging system of the integrated topology. The dual-inverter is the reconfiguration of three H-bridge inverters. The combination of the dual-inverter and the impedance network source is applied to open-end winding induction motor (OWIM) drive system. Charging mode and drive mode can be changed by switching. In practical engineering applications, the connection wire is longer, and the influence of the parasitic parameters is greater on the circuit performance. Hence, the buffer circuit is adopted. The proposed integrated topology of charging and drive has high power factor, electric isolation, single-stage boost/buck function, high reliability, and fault-tolerance. Simulation and experimental results verify the feasibility of the integrated topology. © 2017, The editorial office of Transaction of China Electrotechnical Society. All right reserved.
