| Abstract: | The reason why the no-load voltage of direct current is too high in rectifier unit testing is analyzed. The cause that transition current of DC-load in rectifier unit without balance reactor exceeds the range of permission is discussed. It is concluded that less experimental current than transition current leadsto too high rated DC voltage regulation rate in the test. An equivalent method of how to get rated DC voltage regulation rate by decreasing the rated voltage on the line network is introduced. The main function of the resistor to absorb minor current is also described on the basis of experimental data. |
