This paper proposes the use of a frequency converter used in the AC motor drives to build a fast charging battery converter for electric vehicles (EV). The possibility of using semiconductor integrated modules with two-level inverters and diode rectifiers for the construction of high power voltage DC/DC converters has been demonstrated. The DC voltage of the EV battery during charging is obtained by rectifying the three-phase voltage of the PWM inverter. A 600 V DC microgrid was used to power the inverter. Simulation tests of the DC/DC converter model were carried out. The results of simulation tests were verified experimentally on a laboratory stand.

The paper proposes the adaptation of the industrial plant’s power network to supply electric vehicle (EV) fast-charging converters (above 300 kW) using renewable energy sources (RESs). A 600 V DC microgrid was used to supply energy from RESs for the needs of variable speed motor drives and charging of EV batteries. It has been shown that it is possible to support the supply of drive voltage frequency converters (VFCs) and charging of EV batteries converters with renewable energy from a 600 V DC microgrid, which improves the power quality indicators in the power system. The possibility of implementing the fast EV batteries charging station to the industrial plant’s power system in such a way that the system energy demand is not increased has also been shown. The EV battery charging station using the drive converter has been presented, as well as the results of simulation and laboratory tests of the proposed solution.

Three-phase PWM (Pulse Width Modulation) inverters generate parasitic Differential-Mode Voltages (DMV) and Common-Mode Voltages (CMV). Parasitic voltages are a side inherent effect of using the PWM to shape the phase-to-phase inverter voltage. In this article, authors present a method for filtration of high-frequency harmonics of DM and CM voltages aimed at limiting the parasitic currents: DM voltage—phase-to-phase parasitic current and CM voltage—ground parasitic current. As the final result of the tests, almost complete elimination of leakage parasitic current form PE shock protection system was achieved. To build circuit which allows eliminate capacitance leakage current the earth protection system the two different kinds of double screened cables to supply inverter and motor were used.

In railway tractive vehicles, three-phase PWM (Pulse Width Modulation) inverters generate parasitic Differential-Mode Voltages (DMV) and Common-Mode Voltages (CMV). Parasitic voltages are a side effect of using the width modulation to shape the phase-to-phase inverter’s voltage. In this article, the authors present a mathematical description of the DM and CM voltages and carry out their spectral analysis. Based on the spectral harmonics analysis, the authors present a method for filtration of harmonics of DM and CM voltages aimed at limiting the capacitance parasitic currents: due to DM voltage – phase-to-phase parasitic current and CM voltage – ground parasitic currents. As the final result of the tests, almost complete elimination of leakage parasitic current form PE shock protection system was achieved.

The article presents the results of computer tests of a resonant harmonic filter installed between the solar inverter and the rectifier in the battery charging stations for motor vehicles. The article shows that the reduction of harmonics in the alternating current enables the correct operation of a solar inverter equipped with differential voltage-mode filters (DM) without using a separating transformer behind the inverter. To limit the harmonic content in the alternating current line of the hybrid supply network, a resonant filter was used. The results showed the possibility of feeding the diode rectifier of battery charging converter directly from the solar power inverter without the need usage of separating transformer behind the solar inverter.

Photovoltaic (PV) power systems are described in the article. Power generated from renewable energy sources is not stable because of the energy fluctuations caused mainly by atmospheric conditions. Therefore, in order to improve the parameters and stability of the power system, PV power plants should cooperate with electrical energy storage system such as electrochemical batteries. Moreover, because of the reason that PV power plants are often located on the terrain which is accessible by the man, galvanic isolation may be obligatory. Since the efficiency of the power conversion in PV power systems has to be maximized, soft switched resonant power converters, in which switching losses are minimized, are utilized in such PV power systems. Moreover, grid-connected PV inverter which is a crucial element of the PV power system is presented in the article.

Low voltage frequency converters (VFCs) for ac drives supplied from isolation terra (IT) mains can produce voltage spikes in the supplying mains. The spikes are minimalized by earthed electromagnetic compatibility (EMC) filter which is built in intermediate circuit of VFC. In adjustable frequency drive (AFD) of medium and high power (up to 1MVV) the voltage spikes cause damages of voltage frequency converter. Description, conclusion, experimental and simulation results of AFD with earthed and non earthed EMC filter located in the intermediate circuit are presented in this paper.
