Deadbeat control of Z source inverter with voltage ride-through capability

This paper presents a Z source inverter connected to grid. The effect of voltage sags on ZSI will be studied when two different ac side control schemes are used. The paper compares the performance of both PI control and deadbeat control. The Z-source inverter employs a unique LC network to couple the inverter main circuit to the diode front end. By controlling the shoot-through duty cycle, the Z-source can theoretically produce any desired output ac voltage, even greater than the line voltage. Hence, this inerter topology provides voltage ride through capability under voltage sags. Simulation results verified the effectiveness and reliability of deadbeat control over PI control.
