    • The invention relates to a converter and to a method for determining a current space vector for a converter that can be operated with pulse-width modulation, comprising signaling electronics and a power final stage that comprises power circuit breakers situated in three half bridges each of which comprising a lower and an upper branch. Means for detecting the respective currents are situated either in all three lower or in all three upper branches of the half bridges. At least one associated current sampled value is determined within a time segment by using two of the three means provided for detecting the currents. A current space vector is formed from the current sampled values determined by this pair of means or the current values are formed in the output branches, in particular, for use in a control and/or regulating method. Said pair of means is selected differently according to the output voltage space vector.

    • The invention relates to a converter and method for determination of a current sinor for a converter operated with pulse width modulation, comprising a signal electronic circuit and a power end-stage with a power circuit arranged as three half-bridges each divided into a lower and an upper branch. Means for determining the instantaneous current are arranged in either all three of the lower or all three of the upper branches of the half-bridges, at least one corresponding measured current value is recorded by two of the three means of determining current within a timespan and a current sinor is generated, or the current values in the output branches are generated from said current measured values, measured by the pair of current determination means, in particular for use in a control and/or regulation method. Said pair of means are variously selected depending on the output voltage sinor.
