Aims: Plant growth-promoting rhizobacteria enhance growth by making plant nutrients available to plants under a variety of growing conditions. The study was designed screen zinc (Zn) solubilizing and test their colonization ability in the rice rhizosphere.
 Place Duration Study: experiments were conducted Department Agricultural Chemistry, Bangladesh University, Mymensingh-2202, from Janua...

This paper proposes five level diode clamped Z source Inverter. The existing PWM techniques used for ZSI are restricted for two level. The two level Z Source Inverter have high harmonic distortions which effects the performance of the grid connected PV system. To improve the performance of the system the number of voltage levels in the output waveform need to be increased. This paper presents c...

This paper presents the comparison of Push-Pull Inverter and Z-Source Inverter based Static Compensators (STATCOM).The closed loop system with STATCOM is modeled and simulated using the blocks of MATLAB/SIMULINK.Voltage sag mitigation using Push-Pull Inverter and ZSource Inverter are presented. The present work proposes Z-Source Inverter and Push-Pull Inverter based STATCOM for the control of r...

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...

This paper presents an efficient and fast fault-tolerant control scheme for a bidirectional Z-source inverter (BiZSI)-fed induction-motor drive system vehicular applications. The proposed strategy aims the fault detection, localization diagnosis of during switch failures in module. Generally, power–semiconductor modules occur due to open- short-circuit faults. An modulation is design specificat...
