Efficiency Analysis of Charging Station for Electric Vehicles Using the Active Rectifier in Microgrid System

The article proposes the structure of an electric vehicle charging station with active four-quadrant rectifier in power factor correction mode. The Matlab model of the proposed charging station was built, which takes into account the parameters of the mains supply, the parameters of the switches of the active rectifier and its automatic control system and equivalent model of the battery compartment. The mathematical model of the static and dynamic energy losses calculator which based on a polynomial approximation of the energy dependencies of IGBT modules was created. The analysis of the parameters of the quality of electricity, the components of the energy losses and the efficiency of the charging station on the interval of a full charge of the battery at various charge currents and the frequency of the PWM.
