Abstract

Charging stations are becoming an important part of the modern urban infrastructure. This paper describes a concept of a standalone cost-effective medium power charging station dedicated for electric bus charging. It is based on a voltage-source active rectifier operating in both current and voltage mode supplied by low voltage power grid. Appropriate model and simulation of the station at the power level of 300kW are provided.

Abstract

This article deals with the description of topology configuration of wireless energy transfer system. Wireless energy transfer systems are used in several applications areas as is wireless charging accumulators in electric vehicles, charging batteries in mobiles, in lighting applications and other. This article is focused on wireless charging accumulators in electric vehicles, which the main quality indicators are high transmitted power, high efficiency and the transmission distance in range of the ground clearance of standard vehicles. There are described two topologies, first is series - series compensated system and second is series - parallel compensated system.
