    摘要: A process for supplying a polyphase motor with electronic switching (M) from a voltage supply source (A), includes a passive electric filter downstream of the supply source (A), a conversion of the voltage supplied by the source (A) to supply the phases of the motor (M), using an assembly of controllable switches having either a passing condition or blocking condition, where each combination of conditions of the switches defines a conversion configuration. The process regulates the supply current about a reference current (Iref), and a sequence of magnetization and de-magnetization cycles of the phases of the motor (M) initiated by magnetization or de-magnetization references of the phases. During at least one period of sequencing per cycle, several pairs of conversion configurations are selected so that the mean current conforms as close as possible to the reference current (Iref).

    摘要: A method for powering an electronically switched variable reluctance motor (100) from a single-phase AC voltage source (17) is disclosed. Each phase of the motor is sequentially subjected to a magnetizing sequence, a demagnetizing sequence and an energy transfer to a storage capacitor (C) common to all the phases. Feedback sequences (R) in which the energy stored in the storage capacitor (C) is returned to the rectifier stage (15) are performed by controlling a chopping switch (TH) connected in series to the storage capacitor (C). The method includes a step of monitoring the energy returned to the rectifier stage (15) in order to correct instability in the rectified power supply current (Ia) relative to a reference current wave, and modulating the cyclical chopping ratio around a substantially constant mean value. The method is useful for powering household appliances.
