This paper proposes a three-phase quasi-Z-source matrix converter based induction motor adjustable-speed drives. The quasi-Z-source unique impedance network is utilized to overcome the limitation of the voltage gain of traditional matrix converter. The quasi-Z-source matrix converter can provide buck-boost function by controlling shoot-through duty ratio and modulation index. Analysis base on state-space equation shows the relationship among the shoot-through duty ratio and boost factor as well as voltage gain. Also, the proposed speed control method is able to change the motor speed from zero to the rated speed with the full load torque. The operating principle and system analysis are presented in detail. The simulation results validate the proposed quasi-Z-source matrix converter based adjustable speed drives.
