Abstract

A circuit arrangement for transferring energy includes an energy source, a control device and an energy distribution network. The energy distribution network has a base element and at least one load element. The base element includes a first intermediate circuit energy storage element which can be electrically connected to or disconnected from the energy source via two first controllable switching elements by way of the control device to form a first energy circuit. The at least one load element includes an energy consumer which can be electrically connected to or disconnected from the connections of the first intermediate circuit energy storage element via two second controllable switching elements by way of the control device to form a second energy circuit. The control device is designed to actuate the first and second switching elements of the respective energy distribution network such that that energy is transferred from the energy source to the energy consumer or the reverse, wherein a direct conductive connection between the energy source and the energy consumer does not exist at any time.
