“…In general, the flux linkages variation in the stator phases are sinusoidal but with . Eventual the time pulsation in the torque and current are observed due to harmonics in the d-q model for the 1 [8] is similar to an inverter with singlestage topology. The inverter in general operates and produces low output due to buck operation.…”

“…In the proposed work, the variable speed wind turbine is used to power an Induction motor drive system through an effective power electronic circuit. The Impedance Source inverter (ZSI) [8] is an effective AC-DC-AC converter circuit. The effect of impedance source produces increased efficiency as the zero state switching of an inverter is eliminated.…”

Abstract-In this paper, a Stand-Alone Induction Motor drive is controlled using an Impedance Source Inverter (ZSI). The Permanent Magnet Synchronous Generator (PMSG) is used as the variable speed wind turbine generator for the power generation.The Space Vector Pulse Width Modulation (SVPWM) controls the ZSI switches for generating constant voltage supply for driving the Induction Motor. In the proposed paper, the generator side diode rectifier and the load side ZSI is presented. The variable speed generator is modeled with the mathematical modeling of the PMSG machine equations. The performance of the PMSG obtained is efficient for a drive system. The PMSG designed for a power rating of 4kW. The ZSI eliminates the shoot-through problem and the SVM controlled switching reduces the harmonic contents for a drive application. The performance of the proposed design is verified in the results obtained. The results are generated using the MATLAB 7.

“…Active rectifiers have gained popularity in recent years. This is due to the increasing use of ac to dc converters and also some major drawbacks of their passive counterparts [1,2]. Vienna rectifier is a promising active ac to dc converter due to its reduced switch count and lower voltage stress which in turn lead to a reduced switching loss.…”

This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nature of the Vienna configuration, balancing the output capacitors voltages is inevitable leading to a modified virtual flux based technique. Applying this modification, a separate switching table has been jammed into the proposed technique in order to control the capacitors voltages. Simulation results show the superiority of the virtual flux technique over the conventional Vienna control techniques from point of the mentioned advantages.
