Circuit arrangements for operating a household appliance |
摘要 |
A circuit for operating a household appliance, wherein the circuit includes a switched-mode power supply for converting the power supply of a public power supply network into direct supply voltage. The circuit also includes a controller that is connected to the switched-mode power supply for being supplied with the direct supply voltage and for controlling processes of the household appliance. An EMC filter is provided to protect the public supply network from interference signals from the household appliance. The EMC filter includes a condenser that is connected between a phase conductor pole and a neutral conductor pole of the public power supply network; a bleeder resistor that is connected in parallel with the condenser; and a switch that can be activated by the controller to connect the condenser and the bleeder resistor to the neutral conductor pole. |
