Multi-level inverters (MLI) are power electronic converters that convert DC power to AC power with high power-quality of output voltage waveforms. These MLI are the main streamline converters for integrating dc power of EV with microgrids. Thus, the recent interest of researchers is to investigate the MLI with a lower number of active and passive switch counts which could integrate the DC power of EV to the microgrid with the boosting ability. This chapter discusses various topologies of MLI for the integration of the DC power of EV to the grid for vehicle-to-grid (V2G) applications. MLI converts DC power to AC power with high quality of output voltage waveform. Thus, the recent interest of researchers is to investigate the MLI with a lower number of active and passive switch counts which could integrate the DC power of EV to the microgrid. Also, MLI must be capable of boosting the voltage level to meet the grid requirements. The aim of this chapter is to discuss the various topologies of MLI for the integration of DC power of EV to the grid for vehicle-to-grid (V2G) applications.

The multilevel inverter is attracting the specialist in medium and high voltage applications, among its types, the cascade H bridge Multi-Level Inverter (MLI), commonly used for high power and high voltage applications. The main advantage of the conventional cascade (MLI) is generated a large number of output voltage levels but it demands a large number of components that produce complexity in the control circuit, and high cost. Along these lines, this paper presents a brief about the non-conventional cascade multilevel topologies that can produce a high number of output voltage levels with the least components. The non-conventional cascade (MLI) in this paper was built to reduce the number of switches, simplify the circuit configuration, uncomplicated control, and minimize the system cost. Besides, it reduces THD and increases efficiency. Two topologies of non-conventional cascade MLI three phase, the Nine level and Seventeen level are presented. The PWM technique is used to control the switches. The simulation results show a better performance for both topologies. THD, the power loss and the efficiency of the two topologies are calculated and drawn to the different values of the Modulation index (ma).

Charging of electric vehicles (EVs) on a large scale can cause problems for the grid. Utilizing local flexibility resources, such as smart charging, stationary battery, vehicle-to-grid applications, and local generation can be an efficient way to contain the grid challenges and mitigate the need for grid reinforcement. Focusing on the INSPIRIA charging station located in Norway, this paper investigates the possibility of coping with imminent grid challenges by means of local flexibility. First, the potential grid challenges are estimated with the help of Monte Carlo simulations. Second, cost and performance for the various local flexibility sources are presented. Third, an analysis of the choice of battery, charging process, and battery economy are provided. Finally, the paper discusses the optimal mix of flexibility resources to efficiently mitigate grid challenges at the INSPIRIA charging station.

Now a day mostly we produce power from non conventional energy sources and power hassle increases day by day. To diminish this power demand we need to emphasize power infusion methods. Multi-level inverter is accommodating to infuse power from distinct renewable sources like solar, wind-power. It generates the alternating output level of voltage from different DC level sources. This inverter uses ‘m’ H-bridges and several DC sources to obtain (2m+1) level of output voltage. This paper focuses on improvement of quality of desired output voltage waveforms with less number of switching devices.

Now-a-days most of the appliances and machine works on AC power. If AC power is unavailable for a short period of time, then during that period we need to supply AC power by converting the stored DC power. This can be possible using an Inverter. Inverters can be of multi-phase i.e. 3phase, 5phase, 6phase and so on. Since inverters have wide application in industries and HVDC transmission lines, the improvement in the output voltage and the reduction in harmonics are of utmost importance. In this paper a detailed analysis of harmonics and THD in a five phase inverter with different conduction angle along with the derived mathematical equations has been presented. A comparative study between three phase and five phase inverters at different conduction angle has been presented.

The expansion of electric vehicles made the expansion of charging infrastructure rudimentary to keep up with this developing technology that helps people in a myriad of ways. The main drawback in electric vehicle charging, however, is the time consumed to charge a vehicle. The fast charging of electric vehicles solves this problem thus making it a lucrative technology for consumers. However, the fast charging technology is not without its limitations. In this paper we have identified the technology gaps in EV fast charging stations mostly focused on the extremely fast charging topology. It will help pave a path for researchers to direct their effort in a consolidated manner to contribute to the fast charging infrastructure. A thorough review of all aspects and limitations of existing extremely fast charging (XFC) stations have been identified and supporting data are provided. The importance of DC power network based on free fuel energy sources and silicon carbide-based power electronics are proposed to provide ultra-low cost and ultra-high speed XFC stations.

<p class="Abstract"><span lang="EN-US">Across the year, the needs of Indonesians in the use of electronic equipment are increasing, which results in higher electricity usage. Because most of the electricity load uses AC power, in the application of a DC power source such as solar cells, an inverter that converts DC to AC power is needed. Therefore, the inverter is one of the tools that are widely developed in power electronics. The output voltage from simulation and real hardware is a sine wave with some distortion due to lack of filter; therefore, there occurs a harmonic. The voltage and frequency were also measured with a multimeter. The result shows that both voltage and frequency are closed to the design specification which is 220V 50Hz with the voltage and frequency difference of 1.09% and 0.4%, respectively.</span></p>
