Abstract:
1. A voltage supply for a control device ( 13 ), comprising a voltage source ( 10 ) as well as a voltage converter ( 11 ) having a voltage input ( 111 ) and voltage output ( 112 ), the voltage input ( 111 ) being capable of being connected to the voltage source ( 10 ), wherein a primary part ( 121 ) and secondary part ( 122 ) are provided, the primary part ( 121 ) being connected to the voltage source ( 10 ) and being controllable by the voltage output ( 112 ) of the voltage converter ( 11 ), and the secondary part ( 122 ) comprising a first and a second mutually independent winding, a supply voltage for the control device ( 13 ) being made available by the first winding, the second winding being connected to the voltage input ( 111 ) of the voltage converter ( 11 ) so that a supply voltage for the voltage converter ( 11 ) is implemented by the second winding, wherein the voltage input ( 111 ) of the voltage converter is connected to the voltage source ( 10 ) by a switch ( 14 ) additionally comprised by the voltage supply; and a control output ( 15 ) is configured to transmit a status signal of the switch to the control device ( 13 ).
