The conversion of a direct current in an alternating current having a member for correcting the voltage issued comprising a device for measuring a low frequency component of said voltage, and advantages of the control of such a system

摘要

This conversion system (100) of a direct current to the input of an alternating current of the output, comprising: - at least a voltage inverter (18) which is adapted to convert a direct current of the input of an alternating current of the output, - of the means (20) for controlling the or each inverter (18), - at least one device (98) of the correction of the output voltage delivered by the or each inverter (18), which is adapted to inject a corrective signal (, vvc, vwc) at the input of the control means (20), is characterized in that the or each correction device (98) comprises a measuring means of a component of the voltage delivered by the or each inverter (18) for the frequencies of less than 10 hz, preferably less than or equal to 1 hz, and a computation unit of the corrective signal (, vvc, vwc) as a function of the component of the measured voltage.
