Embodiment Construction

[0065] FIG. 1 shows a schematic block diagram of a circuit arrangement for charging a traction battery 1 of an electric vehicle. The circuit arrangement includes a secondary side inductance 2 (not shown) of the pickup section. The secondary-side inductance 2 receives the magnetic field and generates an electrical output voltage, which is an alternating voltage. In addition, the circuit arrangement comprises a rectifier 3 for rectifying the output voltage of the inductor 2 . The circuit arrangement also comprises a voltage converter 4 which converts the direct or constant output voltage of the rectifier 3 having a given voltage level into a direct or constant voltage having a desired level which is thus determined by Used to charge battery 1. Therefore, the battery voltage U bat equal to the output voltage of the voltage converter 4 .

Abstract

A circuit arrangement for providing a DC voltage in a vehicle, particularly for charging a traction battery 1, comprises at least one secondary-sided inductance 2 of a vehicle-sided pick-up portion for receiving a magnetic field and for producing an electric output voltage, a rectifier 3 for rectifying the output voltage of the at least one inductance, and at least one source element and / or drain element 4. The rectifier 3 and the source element are connected such that an output voltage of the circuit arrangement is a sum of an output voltage (U1) of the rectifier (3) and an output voltage of the source element. The rectifier and the drain element are connected such that an output voltage of the circuit arrangement is a difference between an output voltage (U1) of the rectifier and an input voltage of the drain element. The source element and / or the drain element may be provided by a voltage converter 4 that can be operated in source mode or drain mode, and may be a forward, push-pull or universal converter.

Description

technical field [0001] The invention relates to a circuit arrangement for providing a desired DC voltage, in particular for charging a traction battery in a vehicle. Furthermore, the invention relates to a vehicle, in particular a road vehicle or a rail vehicle comprising said circuit arrangement. Furthermore, the invention relates to a method of operating said circuit arrangement. Background technique [0002] Vehicles, in particular electric land vehicles, can be powered in different ways. One option is to charge the on-board energy storage on the vehicle when the vehicle is stopped and by using a cable connection. According to another option, the energy is wirelessly transferred to the vehicle using a magnetic field that induces a voltage in at least one inductance onboard the vehicle. The expression "pickup" or "receiver" has been used for devices comprising at least one inductance. Electric vehicles may include so-called traction batteries. The traction battery pro...
