Abstract: A DC voltage source, for example an AC/DC converter, has an output producing a controllable DC voltage for a DC charging station to charge the battery of an electric vehicle. A voltage balancing unit is connected between the output of the converter and the output terminal of the DC charging station.

Abstract: To avoid the overexposure and underexposure of pixels which occurs with high image contrasts, each pixel contains a local autoadaptive control. With the help of this control, each pixel automatically ends its integration period as soon as it has integrated enough photoelectric current. An analog signal represents the length of the integration period selected by the pixel. Together with the integrated pixel signal, it represents brightness information with high dynamics and with low requirements regarding the dynamics of the individual signals. Because of their local adaptivity, the image sensors are suitable for all applications where high brightness contrasts must be processed, such as guiding a motor vehicle in highway traffic, nature films and astronomy.
