description: The subject of the following qualifying work is a power factor correction (PFC) boost converter designed to operate as a boosting pre-stabilizer for a lithium-ion battery charger. The purpose of the work is to consider the issue of constructing a PFC converter for a 22 kVA electric vehicle battery charger powered by an alternating current of 380 V, 50 Hz, designed to charge a lithium-ion battery with a maximum voltage of 690 V. Results. In the following qualifying work, it is first shown that, for the specified type of lithium-ion chargers, usage of a PFC boost-type corrector is rational. Then, the purpose and the principles of PFC boost converter design have been analyzed, the choice of output voltage rationalized, and the appropriate topology selected. Computer simulations have been conducted to confirm the functioning of the proposed solution. Field of application. Currently, electric vehicles are increasingly equipped with traction batteries, foremost, electric cars and electric buses. At the same time, in urban electric transport, the so-called in-motion charging technologies are ubiquitous, where the traction batteries are used only in areas without the overhead contact system. Regardless of the application, chargers are required to charge traction batteries. Such charging converters can be powered from contact line voltage, as well as from an industrial network of 380 V, 50 Hz. In the latter case, to reduce the influence of capacitive load, i.e. chargers, as they contain a capacitive filter at the input, it is desirable to use active power factor correctors that, unlike passive devices, achieve a nearly sinusoidal current consumption from the network.
