Abstract
A charging station (10) for charging a plug-in motor vehicle (24) at a charging post (12) has a power transformer (14) and rectifier modules (16). The power transformer (14) has terminal leads (18) that are DC-isolated on the secondary side. The terminal leads (18) are connected at least partially to the rectifier modules (16). The power transformer (14) and the rectifier modules (16) are configured so that the rectifier modules (16) emit a low DC voltage when the power transformer (14) is fed with a medium voltage.
