Abstract
In order to improve the operation of a dc transmission unit (GU) between a rectifier (R) and an inverter (I), an extinction angle signal (LS) of the inverter (I) is fed as reference variable to the rectifier regulator (RR). A current signal (ID) of the dc transmission unit (GU) is preferably fed to an inverter regulator (IR) of the inverter (I) as input variable. In addition, the current signal (ID) can be fed as input variable to the rectifier regulator (RR) for the start-up and/or in the event of a malfunction. Another solution consists of a circuit arrangement (S1, S2, S3) for the carrying out of the method.
Claims14
A method for direct-current transmission between at least one rectifier and at least one inverter, comprising the steps of:
- a) determining an extinction angle signal of the inverter;
- and
- b) feeding the extinction-angle signal of the inverter as an input signal to a rectifier regulator.
A circuit for direct-current transmission, comprising:
- a) a rectifier producing a direct current from an alternating current;
- b) an inverter forming an alternating current from the direct current, and receiving the direct current from the rectifier;
- c) a rectifier regulator being coupled to the rectifier, and having an input;
- d) a first signal generator being coupled to the inverter and providing as an output an extinction angle signal, wherein the input of the rectifier regulator is coupled to the first signal generator.
