SWITCHING PROCESS AND ASSOCIATED CONTROL DEVICE

摘要

This invention relates to a process for switching the voltage supply (12) for an alternating current electric engine (16) between a supply from an ASD (32) and a supply from an electrical network (22), whereby the process comprises a stage for determining an ideal speed of rotation for the electric engine (16) and for synchronising the phase and the amplitude of the voltage delivered by the ASD (32) with the voltage delivered by the electrical network (22).
