Abstract

A transformer apparatus for a charging station for electrically charging vehicles. The charging station includes at least two charging points. The transformer apparatus includes an input connection for electrical connection to an electrical power source. The transformer apparatus further includes at least one primary winding, and connected downstream electrically in series, at least three electrically parallel secondary windings that are DC-isolated from one another. The secondary windings are configured to be connected to at least two output connections of the at least two charging points of the charging station by switching logic. The switching logic connects at least two secondary windings electrically in parallel with a respective output connection of a respective charging point.
