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...

This paper presents a single-phase Z-source inverter as a power conditioning system for a single phase utility connected system. Z-source inverter is a single-stage topology that has buck-boost feature, which is possible because of additional shoot through state introduced in zero state of the conventional inverter pulse width modulation and provides desired output AC voltage. Small distributed...
