examination of pmsm application in eelectric vehicles based on improved bi-directional z quasi-source inverter

This article proposes a variable permanent magnet drive system with dc link voltage based on an improved impedance quasi-source inverter. the proposed inverter for the permanent magnet drive system has improved compared to the prior inverters used in such a system regarding output voltage gain and input current. in addition to functional analysis and dynamic equations, controller design and realization of an improved bilateral impedance quasi-source inverter for use in electric vehicles are also presented. the circuit analysis shows that with a two-way switch in the impedance pseudo-source network, the performance of the inverter under small inductance and low power factor can be improved. in the flux control method, when there is a disturbance in the input voltage of the circuit, the dc link tends to fluctuate, which is considered a defect. to overcome this problem, a dedicated voltage controller is used to remove the disturbance and stabilize the dc link voltage. a non-connection mode is designed. the simulation results are presented to prove the performance of the circuit and the effectiveness of the proposed control method.
