Firstly, through a detailed analysis of the working principle of the voltage-type Vienna rectifier, the mathematical model of the rectifier power control is established according to the mathematical model of the Vienna rectifier based on the equivalent switch function in the d-q two-phase synchronous rotation coordinate system. Secondly, according to the mathematical model of power control, using the principle of direct power control (DPC), the outer loop of the DC bus voltage PI control of the Vienna rectifier is described in detail, the dual loop structure of the direct power control inner loop and the overall system structure. Finally, the control strategy was verified by Simulink simulation. The results show that the Vienna rectifier based on direct power control has good steady state and dynamic performances, and verify the correctness and feasibility of the control strategy.
