Circuit device for providing electrical operation voltage to household appliance e.g. washing machine, has energy storage unit arranged between output terminal and reference potential end, to supply electrical energy during load failure

摘要

The circuit device has input and output terminals (6,4) to which electrical supply voltage (UV) and operating voltage (UB) are applied respectively relative to a reference potential end (5). An energy storage unit (14) is arranged between output terminal and reference potential end, to supply stored electrical energy corresponding to a real time clock during operational failure of an electrical load (2). The input and output terminals are coupled via a FET (8). The drain and source terminals (9,7) of the FET are connected to output and input terminals respectively. An independent claim is included for method for providing operation voltage to electrical load.
