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 no...

In order to study the source limitation and contribution of pre-anthesis assimilates to grain in dual-purpose (forage and grain) barley, a field experiment was carried out in Iran, Ahvaz region. The experimental design was split plot in randomized complete block with three replications. Application rates of nitrogen at four levels (60, 120, 180 and 220 kg.ha-1 N) were as main plots, while sub p...

This paper presents the three topologies of three-phase four-wire DSTATCOM for reduction of harmonics, reactive power compensation, increasing power factor, which occur due to a nonlinear load, environment problem and polluted grid. The performances of the above topologies have been compared for the magnitude of source current, power factor improvement, DC-link voltage regulation, and total har...
