Abstract: A method for operating a power electronic circuit having a first power convertor and at least one second power convertor is specified. The pulse duration-modulated driving of the switches of the circuit arrangement is effected according to a comparison of a reference oscillation with a carrier oscillation. According to the invention, a component of a third harmonic is admixed with the reference oscillation over virtually the entire drive-level range, in particular including low drive-level rates in the range from 20% to approximately 87%. It is also possible to admix a corresponding component of a ninth harmonic in the drive-level range from 20% to approximately 33%. This results in a low clock frequency for the first power convertor and the second power convertor need not have a feedback capability. (FIG. 1)

Abstract: A converter unit is disclosed which produces an output voltage based on reference signals (u*d, u*q) that are generated from active and reactive components (P, Q) of the converter's output power. A first reference signal for a reactive component of the output voltage (u*q) is set to zero, thus regulating the reactive component of the output voltage to zero. Therefore, only the active component is contributing to the actual output voltage. The reference signal for the active component of the output voltage (u*d) is produced based on the active power component (P) with an active power vs. active voltage droop. To synchronize the frequencies of multiple converter units, a reactive power vs. frequency droop can be introduced for each converter unit, regulating the frequency based on changes in the reactive power component (Q) of each converter unit.

Abstract: In circuits with self-commutation such as, for example in inverters (4) for feeding an asynchronous machine (7), a short-time turn-off current impulse is taken from a turn-off capacitor (C1) of a turn-off or common turn-off circuit (3) for interrupting the thyristor current of the inverter. The turn-off circuit (3) connected to the direct-current side (8, 9) of the inverter (4) exhibits a first series circuit of the turn-off capacitor (C1) and a first electrical valve (T2, D2). In a branch in parallel with the turn-off capacitor (C1), a ring-around reactor (L1) with an inductance of 0.1 mH is connected in series with a second thyristor (T1). A further third thyristor (T3) is connected in antiparallel with the second thyristor (T1). A ring-around process initiated by the firing of the second thyristor (T1) is interrupted after a half period. After a freely selectable time, the third thyristor (T3) can be fired and the full resonance cycle can be concluded. As a result, the hold-off interval or minimum turn-off period for the thyristors can be achieved with a comparatively very small ring-around reactor (L1).
