The use of an additional DC/DC converter is unnecessary. Due to the fact that there is no additional link of energy conversion, the reduction of total power losses is achieved. Since the active rectifier is used in the mode of correction of the power factor, there is an improvement in the quality of electricity in the network. Due to the above, the efficiency improves and the emission of higher harmonics of currents and voltages to the mains and the load of the charging station is reduced. Modulation algorithms that increase the quality parameters of the output voltage and output current in active rectifiers are studied. The results of modeling in the form of energy characteristics and radiation indices of higher harmonics of current and voltage to the load and power supply network are obtained.
