Abstract: Household appliance comprising: first power supply lines (4) which are connectable to an AC power supply source (5) for receiving a main electric power (P1) and providing a first AC voltage (V1) and a first AC current (I1). The household appliance, further comprises: a first load (8), and a second load (7) operating by a second voltage (Vcc) lower than the first AC voltage (V1), a master control circuit (12) operating by the second voltage (Vcc), which is configured to generate control signals (SC) to selectively control the first load (8) and the second load (7), and comprises a current sensor (12b) configured to measure the first AC current (I1) and provide a first value (K1(I1) indicative of the first AC current (I1), an inverter device (13) which is electrically connected to the first power supply lines (4) and to the master electronic control circuit (12) to receive the control signal (SC), and is configured to control the voltage supplied to first load (8) based on the control signal. The inverter device (13) further comprises a voltage measurement circuit (13b) configured to measure the first AC voltage (V1) and provide a second value (K2(V1)) indicative of the first AC voltage (V1). The inverter device (13) is configured to provide the second value (K2(V1)) to the master control circuit (12) by a opto-isolator electronic module (15). The master control circuit (12) is configured to determine a third value (K3(P1)) indicative of the main electric power (P1) based on the first value (K1(I1)) and the second value (K2(V1)).
