This paper presents the quasi z-source inverter (QZSI) as an alternate converter system for the wind
generation system. As QZSI inherits the main advantages of traditional Z-source inverter which replaces the
conventional PWM inverter in the system with some of its additional utilities as well. This system will monitor the wind
generator output and adjusts the inverter shoot-through duty cycle employing various boost control technique as per
desired value. Thus, the whole system is modeled and verified through simulation where the system can provide stable
voltage through proper selection of boost factor and has the suitability of maintaining the terminal voltage at desired
level for the direct-driven wind power system.
