Document Type and Number:
WIPO Patent Application WO/2018/024569
Kind Code:
A1
Abstract:
The present invention relates to an electrical household appliance with a power module with dynamically controlled switching frequency. The present invention more particularly relates to an electrical household appliance comprising an electric motor, a driver circuit capable of driving said electric motor, said driver circuit comprising a converter that converts AC mains voltage to DC voltage, a driver circuit inverter stage that inverts the direct current, said driver circuit inverter stage comprising an inverter power module (1 ) having high side and low side power switches (6, 7) with freewheeling diodes (5) in the form of a six-switch three-phase inverter connected to a DC bus, said electric motor being a brushless DC motor and motor position being determined in the manner that currents flowing through motor phases (2, 3, 4) are recreated.
