In this paper, a standalone wind energy conversion system along with switched inductor quasi impedance source inverter is proposed. Wind energy system is chosen because of its sustainability and commercial potential. Permanent magnet synchronous generator is used as there is no need of separate excitation and maintenance. Also Optimum Power technique is incorporated to improve MPPT of wind energy conversion system (WECS).The main objective of this paper is to improve the wind energy conversion system by implementing switched inductor quasi-z-source inverter and battery energy system. Switched inductor quasi-z-source inverter has high efficiency and the input current is continuous, suppresses inrush current and avoids shoot through fault in inverter when compared to Zsource inverter based wind energy conversion system. An effective control technique for the inverter, based on the pulse width modulation (PWM) method, has been developed namely SimpleBoost Modulation technique to balance the line voltages. The proper control of battery current through converter has been done to reduce the electrical torque pulsation of the PMSG under an unbalanced load condition. Index Terms -Permanent Magnet Synchronous Generator (PMSG), Wind Energy Conversion System (WECS), Optimum Power Maximum Power Point Tracking (OP MPPT), switched inductor quasi-z-source inverter, simple boost control.

Multi input-multi output Power electronic interface for hybrid energy resources has gathered much of interest. In this paper, a new configuration for cascade connection of two Z-Impedance networks is presented which is able to extract power from two separate low voltage energy sources such as photovoltaic panels and fuel cell stacks. The required load power can be shared between two sources which may have different low values. The power sharing is controlled by adjusting the shoot through duration and time shifting. The proposed converter includes the features of conventional Z-source converter such as voltage boost and shoot through immunity of the inverter. Steady state operation principles, switching methods and the main relations for power flow from two inputs to the output are derived. A prototype of the converter is built and tested for different operation modes. The results are compared with simulations and theoretical analysis which verify well performance of the system.

“…Which is proposed topology can decrease the size and cost of the capacitor and improves the power density. Where the DC source is series connected with the inductor in proposed series ZSI network, five phase inverter and input source are connected at two sides of the Z-source network [12]. Modulation strategy and inductor current are exactly same for both embedded and series ZSI topology is derived following equation [13] V dc D sh…”

-This paper presents the advance controlling system for multiphase PMBLDC motor. This permanent magnet synchronous motor has copper losses in stator, current vibration and harmonics due to wrong selection of rotor shape is generated by the voltage saturation and more torque ripple. This voltage saturation affects the performance of the motor. The proposed multiphase permanent magnet BLDC motor is to reduce the voltage saturation and also to minimize the torque ripple. The multiphase motor have more handling capacity, high reliability and to produce high torque at same ampere volume of machine. This multiphase topology is requiring high dc source and effective control method for high speed operation. The introduced Z-source topology is used to improve source voltage boost up ability without using any DC/DC converters. Further, it reduces the line harmonics, enhance the load power factor, gives ride through ability in the course of input voltage sags and increases inverter reliability. The IFOC control strategy is possible to achieve high reliable operation at input voltage sag conditions. The proposed Z-source networks as well as IFOC scheme based multi phase motor to attain the minimum torque ripples and high voltage gain in ASD (adjustable speed drive) are analyzed in MATLAB/ SIMULINK environment.
