  • Publication number: 20190326833
    Abstract: A method for regulating an AC output current of a converter having a DC voltage intermediate circuit and a semiconductor switch in a bridge circuit for converting a DC voltage of the DC voltage intermediate circuit into an AC output current. The AC output current is regulated by way of a direct hysteresis current regulation, in which an actual value of the AC output current is maintained within a hysteresis window around a set point value. Furthermore, a hysteresis width of the hysteresis window is modulated in order to adjust a frequency spectrum of the AC output current.

  • Publication number: 20190260309
    Abstract: Disclosed is a method for controlling phase currents of a plurality of three-phase inverters connected in parallel. The phase currents of each inverter are controlled by direct hysteresis current control wherein an actual current space vector for actual values of the phase currents of each inverter is maintained about a target current space vector within a hysteresis window. The measured current space vector of a first inverter is formed by all three phase currents of the first inverter. The actual current space vector of each additional inverter is formed from exactly two phase currents of the respective additional inverter under the proviso that all three phase currents of the additional inverters add up to zero. The selection of the two phase currents from which the actual current space vector is formed, is varied.
