Abstract: The present invention relates to an electrical household appliance comprising at least one synchronous electric motor (11, 12), a driver circuit capable of controlling the speed of said at least one synchronous electric motor (11, 12), said driver circuit comprising a converter that converts AC mains voltage to DC voltage, a DC link and a driver circuit inverter stage (10) that inverts the direct current received from said converter to an AC output signal such that an AC output waveform is produced from a DC power supply.

Abstract: The present invention relates to an electrical household appliance comprising an electronic control board (3) effecting functions of said electrical household appliance and a discharge pump (1), said discharge pump (1) being driven by an electric motor powered by said electronic control board (3) by means of a first switching device (2), the electrical household appliance further comprising a pump driver board (4) controlling the speed of said electric motor by means of a power driver circuit (7) and being powered by the electronic control board (3) by means of the first switching device (2).

Abstract: The present invention relates to a household appliance (1) comprising a control unit (4) that maintains to execute the selected program as much as possible within the discounted rate interval when the user enters the end time (tf) for the selected program, by evaluating the clock (2) data and the momentary energy tariff signal received from the sensing means (3) within the time passing until the end time (tf) and guarantees completion of the program to be executed before the selected end time (tf).

Abstract: The present invention relates to a washing machine (1) comprising a motor (2), a main card (3) that provides the electronic control and a motor card (4) that enables the motor (2) to operate according to the commands provided by the main card (3).
