Circuit for limiting voltage, has limiting network with connection connected with component and another connection connected with supply unit

摘要

The circuit has a limiting network with a connection (102,118,121) and another connection (103,119,122). The limiting voltage drops at a provided component. The former connection is connected with the component and latter connection is connected with the supply unit. The component has two condensers (104,105,116), which are switched into row with one another. The center tap (123) is connected between the condensers with the former connection of the limiting network (101). An independent claim is also included for a method for operating a circuit.
