Spannungsabwärtswandler und denselben benutzendes, von einem Einphasennetz gespeistes, asynchrones Betriebssystem |
摘要 |
The convertor employs pairs of single-phase rectifiers (1,6) with forced switching which are fed from secondary windings (3,5) of a main traction transformer (T). Energy from a DC network passing through the transformer is recovered from one secondary winding (5) by the rectifier (6) working in voltage-boosting mode. The other rectifiers function synchronously as voltage invertors with the primary winding (7) of the transformer open-circuited. The output DC voltage (S) is maintained at a value slightly greater than half of the input voltage (E). |
