Control device with integrated energy conditioning and integrated energy management

A control device (1) with integrated energy conditioning and integrated energy management for actuating an electrically operated and/or controlled actuator (2), the control device (1) comprising:

• a controller (4) for generating an actuation signal for the actuator (2);
• a connection (A-C) for connecting the control device (1) to an external electrical energy supply that provides a grid voltage (VAC0);
• a circuit arrangement (8) for the conditioning, rectification and conversion of the grid voltage (VAC0) into a first intermediate circuit DC voltage (VCC1), wherein a level of the first intermediate circuit DC voltage (VCC1) is independent of a level of the grid voltage (VAC0);
• and
• at least one electrical buffer store (7) for the first intermediate circuit DC voltage (VCC1) for buffering a power necessary for maintaining at least one further voltage (VCC2, VCC3), derived from the first intermediate circuit DC voltage, for supplying power to the controller (4) in the event of failure of the external electrical energy supply and for transferring the actuator (2) to a safe state, in an event of failure of the external electrical energy supply.
