The present invention relates to a method of supplying optimal power for an alternating current electric motor driven by a direct/alternating and alternating/direct/alternating static frequency converter, as well as a device implementing this method. This method of supplying optimal power for an inductive-type load coupled to an application, this load being driven by a static converter controlled by an electronic module, this power supply method constituting the electronic load control device which, at any instant, delivers to the load, by means of setting parameters applied to the controls of the converter, a voltage, by noting the direction of variation around an extreme, corresponding to a minimum power absorbed by the load, from one or more monitoring parameters (MP) which are weighted and/or combined together. The method of supplying optimal power, as well as the device implementing it according to the present invention, apply to all types of load of an inductive nature.

Method and system for supplying optimal power to an inductive-type load

A method of supplying optimal power for an alternating current electric motor driven by a direct/alternating and alternating/direct/alternating static frequency converter including a device for implementing the method. In particular, the method supplies optimal power for an inductive-type load coupled to an application with the load being driven by a static converter controlled by an electronic module. The method involves delivering power to the load by setting parameters which are applied to the controls of the converter and by noting the direction of variation around an extreme, corresponding to a minimum power absorbed by the load on the basis of one or more monitoring parameters which are weighted and/or combined together.
