Power quality issues have recently become a source of major concern due to the large increase in load demand and the addition of various sources of disturbance at the distribution level. Power quality mainly refers to voltage quality. Sudden load variations can lead to a fall in the line voltage magnitude, creating what is called a voltage sag. Many solutions have been proposed and implemented for voltage sag compensation. Power electronics-based solutions such as grid-connected converters and AC/DC schemes are considered basic units for transient voltage fault ride-through capability. This paper describes a multifunctional intelligent bidirectional electrical vehicle (EV) charger that is able to charge the EV battery at different power ratings in addition to voltage sag compensation. The performance of the proposed system is verified and validated through MATLAB/Simulink simulations (R2020A). The proposed solution can effectively meet three main requirements: charging the EV battery at different power ratings, detecting the voltage sag event, and providing the required active and reactive power compensation for voltage sag compensation.

“…MLIs can share the input DC-link voltage on the power switches and decrease the standing voltage of power semiconductors than two-level inverters. The other advantage of MLI provides a large number of levels that lead to having a lower voltage distortion, as well as MLIs, have lower dv/dt, and lower common-mode voltage [3], [4]. Therefore, MILs can be applied in Renewable Energy Sources (RES), Variable Frequency Drives (VFD), Flexible Alternating Current Transmission System (FACTS) Devices, and Electrical Vehicles (EV) [5], [6].…”

This article proposes two generalized multilevel inverter configurations that reduce the number of switching devices, isolated DC sources, and total standing voltage on power switches, making them suitable for renewable energy sources. The main topology is a multilevel inverter that handles two isolated DC sources by ten power switches to create twenty-five voltage levels. Based on the proposed main topology two generalized multilevel inverters are introduced to indicate flexibility in designing and also to minimize the number of elements. The optimal topologies for both extensive multilevel inverters are derived from different design objectives such as minimizing the number of elements (gate drivers, DC sources), achieving a large number of levels, and minimizing the total standing voltage. The main advantages of proposed topologies are a reduced number of elements than other multilevel inverters based on the comparison studies which is performed among the proposed topologies and other topologies. The power loss analysis and standalone PV application of the proposed topologies are discussed. The experimental results are presented for the proposed topology to demonstrate the correct operation of the proposal.INDEX TERMS single-phase multilevel inverters; generalized topologies; cascaded multilevel inverters; symmetric and asymmetric operations, renewable energy sources, photovoltaic system.
