METHOD FOR CONTROLLING THE POWER SUPPLY OF A THREE-PHASED ELECTRIC MOTOR FROM A DC VOLTAGE SOURCE AND DEVICE FOR IMPLEMENTING SAME

摘要

The invention relates to a method for controlling the power supply of a three-phased electric motor (16) from a DC voltage source (14), that comprises the step of determining operation conditions of the motor in which values are allocated to parameters (id*, iq*) for controlling the motor corresponding to said operation conditions, characterised in that it comprises: a test step for determining if the values allocated to the control parameters are adapted to a characteristic of the DC voltage source; if the test step is negative, the step of modifying the values allocated to control the parameters; and the step of operating the motor in the operation conditions defined by the values allocated to the control parameters.
