摘要：

A new electric vehicle (EV) integrated driving and charging topology was designed. The mathematical model of three phase open winding permanent magnet synchronous motor (TPOW-PMSM) in the two-phase rotating d and q coordinate system was established. The voltage space vector distribution of two parallel inverters supplied by a single power supply was analyzed. When the system is in normal operation state, a medium vector hexagon (MVH) space vector pulse width modulation (SVPWM) control strategy was adopted, the speed and current double closed-loop vector control system was designed, which could realize non-zero-sequence voltage operation of the system. Taking single-tube fault and fault phase open-circuit as an example, the voltage space vector distribution after fault of two parallel inverters was studied, and the two parallel inverters could be topologically reconstructed into two-phase 2H-bridge inverter. An improved small vector hexagonal (SVH) SVPWM control strategy was proposed and the implementation method was given. The simulation waveforms and experimental results of TPOW-PMSM system show that the proposed control strategy can ensure the TPOW-PMSM system to keep good operation before and after fault tolerance. The effectiveness and correctness of the proposed control strategy is verified, which guarantee the reliable operation of the system. © 2020, Jilin University Press. All right reserved.
