Title (EN) CONTROL OF PHASE CURRENTS OF AN INVERTER
(FR) RÉGULATION DE COURANTS DE PHASE D'UN ONDULEUR
(DE) REGELUNG VON PHASENSTRÖMEN EINES WECHSELRICHTERS
Abstract:
(EN) The invention relates to a method for controlling phase currents (iU_WR1, iv_WR1, iw_WR1) of a three-phase inverter (WR1), the phase currents (iU_WR1, iv_WR1, iw_WR1) of the inverter (WR1) being controlled by way of a direct hysteresis current control and a selected phase of the inverter (WR1) being additionally switched depending on a zero system current (i0_WR1) of the inverter (WR1).
(FR) L'invention concerne un procédé de régulation de courants de phase (iU_WR1, iv_WR1, iw_WR1) d'un onduleur triphasé (WR1), les courants de phase (iU_WR1, iv_WR1, iw_WR1) de l'onduleur (WR1) étant régulés au moyen d’une régulation directe du courant par hystérésis et une phase choisie de l'onduleur (WR1) étant commutée en plus en fonction d'un courant de système homopolaire (i0_WR1) de l'onduleur (WR1).
(DE) Die Erfindung betrifft ein Verfahren zur Regelung von Phasenströmen (iU_WR1, iv_WR1, iw_WR1) eines dreiphasigen Wechselrichters (WR1), wobei die Phasenströme (iU_WR1, iv_WR1, iw_WR1) des Wechselrichters (WR1) mit einer direkten Hysteresestromregelung geregelt werden und eine ausgewählte Phase des Wechselrichters (WR1) zusätzlich in Abhängigkeit von einem Nullsystemstrom (i0_WR1) des Wechselrichters (WR1) geschaltet wird.
