Improved SVPWM Control Strategy for Tow Level Inverter for Electric Vehicle applications

The conversion of electric power from Direct Current (DC) to Alternating Current (AC) is essential in Electric Vehicles (EV), PhotoVoltaic (PV) generation as a Renewable Energy (RE) source, and Micro-Grids (MGs). To improve the power quality and efficiency in EVs, this paper focuses on modifying the SVPWM technique to minimize the harmonic level, increase the DC voltage utilization ($V_{ut}$) and reduce the switching power loss. The proposed method will be compared with other methods. The simulation results demonstrate that the proposed SVPWM (named Full-SVPWM) algorithm is more effective in terms of power losses, total harmonic distortion (THD), and $V_{ut}.$ Index Terms--Electric vehicle, SPWM, SVPWM, Three-phase power converter, Switching losses, THD.
