This paper presents a methodology to apply a novel space vector pulse width modulation control for three phase Z-source inverter. The space vector modulation for the conventional voltage source inverter is modified so that the additional shoot-through states are inserted within the zero states. So zero voltage time period is diminished for generating a shoot-through time, and active states are ...

Photovoltaic (PV) power systems are increasingly being used as renewable generation sources. Quasi-Z-source inverters (qZSI) a recent, high-potential technology that can be to integrate PV into AC networks. Simultaneously, concerns regarding the stability of increasing. Converters reduce damping grid-connected converter systems, leading instability. Several studies have analyzed and dynamics qZ...

ABSTRACT—The Z-Source Inverter (ZSI) overcomes the disadvantages of the traditional Voltage-Source Inverter (VSI) and Current-Source Inverter (CSI).It can buck and boost its output voltage by utilizing the shoot-through state which is forbidden in traditional VSI. Different Pulse Width Modulation (PWM) techniques are available for the control of Z-Source Inverters. In the traditional PWM techni...

in this paper optimal torque control (otc) of stand-alone variable-speed small-scale wind turbine equipped with a permanent magnet synchronous generator and a switch- mode rectifier is presented. it is shown that with otc method in standalone configuration, power coefficient could be reached to its maximum possible value, i.e. 0.48. an appropriate control algorithm based on turbine characterist...
