The method involves switching a self-locking switch (T1-T4) on depending on one or more conditions, including the induced voltage (UEMK) in the connected winding being of the same sign as the supply voltage, the induced voltage being of the same sign and smaller than the supply voltage and the induced voltage being in a defined angular range relative to its null crossing and of the same sign as the supply voltage. An independent claim is also included for the following: (a) a single-phase AC supplied synchronous motor. |
