Abstract (en)
[origin: WO2016206725A1] A laundry treatment machine (100; 400) or a dishwasher is provided, comprising: - a washing and/or drying assembly configured to carry out washing and/or drying cycles; - an electronic unit (190) configured to drive the washing and/or drying assembly to carry out the washing and/or drying cycles, wherein: - the washing and/or drying assembly comprises a device (170; 177; 450) adapted to be operated by, or comprising, an electric motor; - the electronic unit (190) comprises a power supply apparatus (200) for supplying electric power to the electric motor, the power supply apparatus (200) comprising: - a TRIAC (205) comprising a first anode terminal (M1) coupled with a first terminal (TN) of an AC electric power supply and a second anode terminal (M2) coupled with a first terminal of the electric motor, the electric motor comprising a second terminal coupled with a second terminal (TL) of the AC electric power supply for receiving a supply voltage; - a controller (215) configured to generate a driving signal, and - a triggering circuit (208) for activating the TRIAC (205) by providing triggering pulse signals to a third, gate terminal (G) of the TRIAC (205) based on the driving signal received from the controller (215); - the electronic unit (190) further comprises: - a sensing unit (260) configured to sense the voltage at the second terminal (TL) of the AC electric power supply and to provide a corresponding sensed supply voltage to the controller (215), - a current monitoring circuit (235; Ri) configured to sense the current flowing across the TRIAC (205) and comprising a mean absolute value circuit (235) configured to generate a corresponding processed signal based on the mean absolute value of said current, wherein the controller (215) is further configured to: set the driving signal for activating the TRIAC (205) with a firing angle based on the sensed supply voltage, based on the processed signal and based on an electric motor target voltage in such a way to supply the electric motor with a corresponding operating voltage, such operating voltage being lower than or substantially equal to said supply voltage.
