The invention relates to a clocked energy converter (76) for supplying energy of an electronic control unit (14) of a household device (10), comprising an electronic switch element (16), at least one magnetic and at least one electrical energy storage means (18, 20), a first connection (26) for connecting to an electrical DC voltage source (24), a second connection (22) for connecting to the electronic control unit (14), a clock (32) for controlling and operating the electronic switch element (16) in a switching operation, and a voltage regulation unit (34, 36, 38) connected to the clock (32) for providing a control signal (44), wherein the clock (32) is designed to clock the switch element (16) in accordance with the control signal (44), and wherein the voltage regulation unit (34, 36, 38) is designed to detect an output DC voltage (40) at the second connection (22), to compare with a first predetermined comparative value, to form a first comparative result therefrom, and to provide the clock (32) with the control signal corresponding to the first comparative result. According to the invention, a current detector unit (42) is provided, which is designed to detect an electrical current directed to the control unit (14) via the second connection (22) of the energy converter (76), to compare with a second comparative value, to form a second comparative result therefrom, and to activate or deactivate the control signal (44) in accordance with the second comparative result, wherein the second comparative value is selected to limit a maximum output power of the energy converter (76) to a predetermined value. |
