Vehicle to Grid technology allows the batteries of electric vehicles to operate as energy storage elements for renewable energy power systems. The Z-Source inverter is a new and attractive topology for the power electronics interface. In this paper, the equivalent DC-link voltage ripple of a single-phase Z-Source inverter for Vehicle to Grid applications is analyzed in this paper before derivin...

This paper presents a three-phase four-wire Shunt Active Filter that compensates power quality problems and can also interface renewable energy sources with the electric grid. The inverter stage of the active filter is based in a two-level four-leg inverter and its control is based in the Theory of Instantaneous Reactive Power (p-q Theory). The filter is capable of compensating power factor, un...

A novel modified space vector pulse width modulation (MSVPWM) strategy for Z-Source inverter is presented. By rearranging the position of shoot-through states, the frequency of inductor current ripple is kept constant. Compared with existing MSVPWM strategies, the proposed approach can reduce the maximum inductor current ripple. So the volume of Z-source network inductor can be designed smaller...

This work deals with the design and implementation of a training module for three phase induction motor control, which was divided in the design of: the isolation stage, the drivers, the power inverter and the control source. The simulation was carried out in Matlab to determine the system behavior and for the generation of the waveforms which is finally implemented using the VHDL code in the c...

This paper presents an optimization of the electric power quality by designing a 9 steps multilevel power inverter, which adopts a multi-PWM optimized using genetic algorithms (GA), and minimizing Total Harmonic Distortion (THD) of the first 50 harmonics to about 0%. This optimization is considered an alternative technique because it reduces the expression used to quantify TDH numerically. Part...

The DC/AC inverters are used in grid-coupled Photovoltaic (PV) energy fabrication systems as the power meting out interface between the PV power source and the electric grid. Compared to the grid-coupled PV inverters that have galvanic separation (either on the DC, or on the AC side),the transformer-less PV inverters have the advantages of lower cost, higher efficiency, smaller size and lower w...

Many real-world systems are governed by the timedependent, nonlinear differential equations. Dynamics of an electrical system are also best described using the very equations. Being one of the preferred machines when using advanced control algorithms for electric drives, DC motor has been selected for position tracking. Defining dynamic equations of the motor derived from the theory of nonlinea...

This paper focuses on the design of power management strategy for four-wheel independent drive electric vehicles (4WID EVs). Since the efficiency of the motor and inverter is different under different driving conditions, genetic algorithm based optimal energy management strategy is proposed to maximize the efficiency of motor drive systems. Not only the efficiency of motor, but also the efficie...

This paper presents a comprehensive review on three basic types of multilevel inverters i.e., diode-clamped, flying-capacitor, and cascaded H-bridge multilevel inverter and their variation for photovoltaic power system. The electrical power generated form photovoltaic power system is in DC form. Hence, it is necessary to be controlled and converted to useful form. Inverter is a power electronic...
