METHOD FOR GENERATION OF STANDBY MODE SIGNAL FOR ELECTRIC CONTROL DEVICE Russian patent published in 2012 - IPC D06F33/02 G05B24/02 G06F1/32 H02M7/02 

FIELD: electricity.

SUBSTANCE: first power supply unit (1) on the side of the primary circuit is designed to be a static power supply unit connected to the electric mains (L, N); on the output side it is designed to ensure supply of power to a LV control device. Switchover to active or standby mode is implemented using an activation/deactivation input (E) through connection or disconnection of the LV changeover signal (S). The LV changeover signal (S) is generated, at least, in the standby mode of the first power supply unit (1) with the help of an additional LV power supply unit (3), such signal supplied from the LV output (A) of the additional power supply unit (3). Connection and disconnection of the LV signal (S) to/from the activation/deactivation input (E) of the unit (1) is implemented with the help of a LV switch (5). Additionally, the invention relates to the electric control device LV power supply circuit (3, 5) for such method implementation and to a household appliance containing the said method implementation circuit.

EFFECT: reduced energy consumption and maintenance convenience.
