Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 - 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, characterized in that said synchronous electric motor ( 11 ) is a single-phase synchronous electric motor ( 11 ), a first terminal of the winding of which is connected to a neutral point N ( 9 ) between two capacitors ( 7 , 8 ) of a half-bridge voltage source inverter, the other terminal of the synchronous electric motor ( 11 ) being connected to a point in between two power switches T 1 and T 3 ( 1 , 3 ) connected in series. 2 - An electrical household appliance as in claim 1 , characterized in that said electrical household appliance comprises a second synchronous electric motor ( 12 ) being a three-phase synchronous electric motor ( 12 ) to which a three-phase voltage output is provided by said driver circuit inverter stage ( 10 ) such that the DC link of said half-bridge voltage source inverter is additionally connected with a four-switch three-phase voltage source inverter. 3 - An electrical household appliance as in claim 2 , characterized in that said four-switch three-phase voltage source inverter's two output phases are directly connected with the inverter legs and the third output is taken from the midpoint of the two capacitors ( 7 , 8 ). 4 - An electrical household appliance as in claim 2 , characterized in that said half-bridge inverter and said four-switch three-phase inverter are connected to the same DC link. 5 - An electrical household appliance as in claim 3 , characterized in that said half-bridge inverter and said four-switch three-phase inverter are connected to the same DC link.
