Aiming at the problems of large power ripple, high harmonic components and DC bias on the AC side of the three-phase voltage rectifier Direct Power Control (DPC), as well as the shortcomings of the voltage output of the DC side busbar, the direct power control method of the cross-compensated virtual flux double switch meter has been proposed. The virtual flux can realize the sensorless mode on the input side of the circuit to reduce the high harmonic, even if the first-order low-pass filter is used to replace the integration region, there is still some error. On this basis, the two filters are connected in parallel for virtual flux compensation, and then the voltage vector is selected according to the instantaneous power change, and the sector is re-divided with the voltage as the control vector, and two independent switching state tables are designed. The cross-compensated virtual flux double-switch meter DPC is simulated and compared with the traditional DPC waveform, and the experimental results show that the cross-compensated virtual flux double-switch meter DPC strategy can effectively reduce the proportion of harmonic content, control power fluctuations, improve DC bias, has fast tracking effect, stabilize output voltage, and control active and reactive power flexibly. The three-phase voltage rectifier circuit occupies an important position for the pre-rectifier part of the charging power supply of electric vehicles, and the rectifier circuit that can stabilize the output DC voltage cannot only extend its service life for the charging power supply, but also reduce harmonic pollution.
