Method and system for controlling electronic converters

Abstract

A method for controlling an electronic converter, includes: for each of the phases of the electronic converter, measuring an instantaneous current and an instantaneous voltage of the electronic converter; calculating, from the current measurements and voltage measurements: an active power exchanged by the electronic converter and an effective value of voltage of the electronic converter; calculating an effective value of voltage imposed by the conversion step of the electronic converter. The load angle or a load angle-dependent parameter is obtained from the active power, the effective value of voltage and the effective value of imposed voltage; the frequency of a voltage set-point that must be generated by the electronic converter is calculated from the load angle or the load angle-dependent parameter; and the voltage set-point to be generated by the electronic converter is obtained. A system for controlling an electronic converter to carry out the method is also provided.
