  Due to the growing popularity of renewable energy sources, grid-connected inverters are becoming more and more common in distributed microgrid and smart-grid system. The appropriate characteristics of Quasi-Z-source inverters (QZSI), including continuous input current, common DC rail, and high voltage gain, have made these inverters widely used in the renewable energy system. A battery is necessary for renewable energy systems in order to store energy when the demand for power is low. IN this study a configuration involving a battery across one of the capacitors on the DC side is proposed, through which the DC control loop is adjusted. Also, Interconnection-Damping-Assignment Passivity-Based Control (IDA-PBC)approach has been used to adjust the battery current/voltage and the output voltage. Compared to other controllers, the proposed controller can provide faster response and better stability for QZSI when the variation of input and load. In addition, the proposed controller is not sensitive to the system’s initial operating point and is global asymptotic stability. The simulations and theoretical design show the effectiveness of the proposed controller. پرونده مقاله

  In this paper, a new circuit is proposed for step-up Z-source inverter based on QZSI (quasi-Z-source inverter). The proposed topology inherits all advantages of the conventional topology. The proposed topology in comparison with conventional topology reduces the ST (Shoot-through) duty cycle by over 25% at the same voltage boost factor. Theoretical analysis of the proposed qZSI in the ST and non-ST operating modes is described. Then in order to show the performance of the proposed ZSI, the simulation results on PSCAD software are used. پرونده مقاله
