Abstract (en)

[origin: FR2779587A1] The invention concerns a method for powering a polyphased electric motor with electronic switching (M) from a live power source (A), comprising a passive electrical filtering downstream of the power source (A), a conversion of the voltage supplied by the source (A) for powering the motor (M) phases, using a set of controllable switches presenting either an on-state, or an off-state, each combination of switch states defining a conversion configuration, regulating feeding current based on a current set value (Icons), and a sequence of magnetisation and demagnetisation cycles of the engine (M) initiated by set values for magnetising or demagnetising the phases. Said method further comprises, for at least a cycle sequencing period, several conversion configuration couples so that the supply average current best observes the current set value (Icons). The invention is useful for powering electrical household appliances.
