abstract

  • 2013 John Wiley & Sons, Ltd. Summary A new type of three-phase quasi-Z-source indirect matrix converter (QZS-IMC) is proposed in this paper. It uses a unique impedance network for achieving voltage-boost capability and making the input current in continuous conduction mode (CCM) to eliminate the input filter. The complete modulation strategy is proposed to operate the QZS-IMC. Meanwhile, a closed-loop DC-link peak voltage control strategy is proposed, and the DC-link peak voltage is estimated by measuring both the input and capacitor voltages. With this proposed technique, a high-performance output voltage control can be achieved with an excellent transient performance even if there are input voltage and load current variations. The controller is designed by using the small-signal model. Vector control scheme of the induction motor is combined with the QZS-IMC to achieve the motor drive. A QZS-IMC prototype is built in laboratory, and experimental results verify the operating principle and theoretical analysis of the proposed converter. The simulation tests of QZS-IMC based inductor motor drive are carried out to validate the proposed converter's application in motor drive.
