Abstract (en)
[origin: WO2023052417A1] The invention relates to an ophthalmic laser system (14) comprising at least one electrical load element (20) and a device (10) for controlling an electrical energy supply for the electrical load element (20). The device (10) for controlling an electrical energy supply comprises a first switching element (18a) which switchably connects a voltage source (16) and the at least one load element (20), and a second switching element (18b), which switchably connects the at least one load element (20) and an earth potential (22). In addition, the device comprises a current limiter (24) which is configured to determine a current flow between the voltage source (16) and the first switching element (18a) and to control a switching state of the first switching element (18a) depending on the determined current flow. Moreover, the device (10) comprises a gate driver (28) which is configured to control a switching state of the second switching element (18b) depending on an electrical potential of the at least one load element (20). The current limiter (24) and/or the gate driver (28) are configured to switch the first switching element (18a) and the second switching element (18b), respectively, to an open state when a predefined threshold value of the electrical current flow between the voltage source (16) and the first switching element (18a) is exceeded. The invention also relates to a device (10) for controlling an electrical energy supply and to a method for providing and interrupting an electrical energy supply.
